Martin Beale Memorial
A symposium will be held at the
Royal Society, London, July 6 8, 1987,
in memory of Professor E.M.L. Beale,
sponsored by Imperial College, the
Institute of Mathematics and its
Applications, the Institute of Stat-
isticians, the Mathematical Pro-
gramming Society, the Operational
Research Society, the Royal
Statistical Society, and Scicon
Limited. He was active in all of these
organizations, and their span reflects
not only the breadth of his interests
but also that his achievements ranged
from academic research to real
applications. Much of his career was
motivated by the needs of commerce
and industry; his learned contributions
extended greatly the range of real
problems that can be solved; and he
was highly successful at applying
computer calculations to investigate
mathematical models. The aim of the
symposium is to consider such work,
particularly the interactions between
its various parts.
The invited speakers include: K.C.
Bowen (Royal Holloway College),
G.B. Dantzig (Stanford University),
P.J. Green (University of Durham), P.
Hughes (Logica plc), A. Orden
(University of Chicago), B.D. Ripley
(University of Strathclyde), J.A.
Tomlin (Ketron Inc.), and A.N. Other.
Further, S. Vajda (University of
Sussex) will be the after-dinner
speaker. A number of submitted papers
will also be accepted. The invited
papers will be addressed to all
participants, but the contributed ones
may be specialized, as they will be
presented in parallel sessions and will
be allocated only 25 minutes each
including discussion. If you wish to
contribute a paper, you are invited to
send a summary of about 500 words to
Mrs. B.A. Peberdy (Scicon Limited,
)Vavendon Tower, Wavendon, Milton
Keynes MK17 8LX, England) to arrive
no later than March 1, 1987; not more
than 36 submitted contributions can be
included in the programme.

Network Flows and Monotropic Optimization
By R.T. Rockafellar
John Wiley, New York, 1984
Flows in networks form a class of mathematical programming
problems in which duality plays a central role in computation,
theory and interpretation. Starting from flows and potentials in
networks, the author unfolds the underlying combinatorial
structures and convexity properties and shows that these notions
govern a much broader area of mathematical programming,
including linear programming and problems where a
preseparable convex function is minimized subject to linear
constraints. (A convex function is called preseparable if it is the
sum of linear functions composed of convex functions of a single
variable.) He calls this latter optimization problem "monotropic
programming problem," since convex functions of a single
variable vary in one direction only.
The main objective of this book is to forge theoretical links
between problems and procedures that might seem quite
different at first glance, namely network programming, linear
programming and its generalization to oriented real matroids as
well as monotropic programming in its general form. As by-
products many contributions to classical fields and beyond are
presented, for example, a thorough treatment of network flow
problems with nonlinear costs as well as extensions of the simplex
method and of the out-of-kilter method to general piecewise
linear programming. Further, the theory of conjugate convex
functions is developed in a constructive manner with numerous
examples and applications.
The book is organized into eleven chapters: 1. Networks; 2..
Paths and Cuts; 3. Flows and Capacities; 4. Analysis of Flows; 5.
Matching Theory and Assignment Problems; 6. Potentials and
Spans; 7. Networks with Linear Costs; 8. Optimal Flows and
Potentials; 9. Algorithms for Convex Costs; 10. Linear Systems of
Variables and 11. Monotropic Programming.
Every chapter contains exercises (with additional material)
and ends with supplementary comments and references. This
clearly and well-written monograph will serve as an important
contribution which reveals common structures in mathematical
programming governed by duality.
Discrete Computational Structures
By R. Korfhage
Academic Press, London, 1983
Anyone writing an introductory text for a mathematics or
computer science class is in a dilemma: Is it better to restrict
interest to a small number of topics and study them in depth or to
deal with many themes superficially to keep the book portable?
This book is of the second kind, but it avoids tedious
sequences of definitions. The dilemma mentioned above is
reflected by the fact that some of the (algebraic) chapters in the
first edition have been replaced in this second edition by
chapters treating more current topics and that the word
"polynomial" occurs nowhere in the book in an algebraic context.
The first part presents numerous algebraic structures
together with their machine realizations. The author makes clear
by several examples how much the efficiency of some
manipulations may depend on the particular representations of
The second part of the volume is devoted to the foundations
of computability and logic and contains introductions to
automata and formal language theory, Boolean algebra, and
propositional and predicate calculus.
The author's style is fluent and readable. The text is nearly
free of formal argument. The main work is relegated to the

exercises, many of which are solved in an appendix.
The book makes evident what mathematics and computer
science can do for one another and should therefore motivate
both mathematics and computer science students to examine
interesting topics in detail. However, this is prevented by the poor
reference lists at the end of each chapter.
The Equivalence of Some Combinatorial
By P.F. Reichmeider
Polygonal Publishing House, Washington, 1985
In this work the author explores a set of classical results in
ombinatorics the theorems by Hall, K6nig, Dilworth, Menger
and Ford and Fulkerson which are typically called matching
theorems. A number of (different) proofs, the historical and the
most elegant ones, are presented.
Of course, the results are not new. On the contrary, these
theorems appear in every first course on combinatorics and
graphs. Yet, the primary interest and the value of this book is the
comprehensive discussion of the relationships that exist between
them. Even the fact that these theorems have equivalencies is
well known, and proofs that two specific candidates are related
could be located in the literature. However, what makes this
booklet a nice and welcome contribution is the organisation of
this deep relationship into one compact and really appetizing
Active Set Analysis and Computer Programs
By M.J. Best and K. Ritter
Prentice Hall, Hemel Hempstead, 1985
In the preface the authors state: "The essential idea of a
solution method for a linear programming problem is to move
om one extreme point of the feasible region to an adjacent one
.n such a way as to improve the objective function value. In
virtually any presentation of the subject, this is illustrated by
graphical examples. Our method of presentation is new in that it
is based on a direct generalization of this geometric notion." This
generalization is the active set analysis.
Although computationally equivalent to the simplex method,
active set analysis provides a clearer understanding of the
mechanics of the method and as such it is a valuable educational
Combined with the very nice printing, the readable style of
writing, a good choice of more advanced topics (GUB, parametric
programming, Bland's rule) and some nice descriptions of
models for applications, there is ample opportunity for
recommendation of this volume. But I have doubts on two points:
First, who is the intended audience? This book is certainly not
intended for either users (too technical) or researchers (too
simple) of LP. Also, in my opinion, business and engineering
students are far better off with a textbook that stresses model
formulations and use of input for and output from LP software,
instead of algorithmic details. The only group for which the text
might be suitable is undergraduate students of mathematics. But
for them I would certainly hope an additional textbook is used to
illustrate what one can do with LP.
Second, one third of the book is an appendix, listing the
computer programs (FORTRAN) of the algorithms described.
While the presentation of the programs is well done (more
comments could be inserted in the coding), its relevance and use
are limited at best. Who copies his own LP codes? Who studies
LP coding in a textbook? I would be surprised if more than a
handful of readers do so.
It seems to have grown into a habit to include listings of
computer programs in a textbook. However, if the programs do
not form an integral part of the course in which the book is used,
they only serve to show that the author can write a computer
In summary, Best and Ritter have produced a good looking
textbook with a nice educational starting point, of which the last
one third is virtually useless and for which the audience is limited.

Integer Programming and Related Areas:
A Classified Bibliography 1981-1984
Lecture Notes No. 243
Edited by R.v. Randow
Springer, Berlin, 1985
This book constitutes the fourth volume of the bibliography
on integer programming and related areas. It covers the following
subjects: theory and methods of general integer programming,
combinatorial and graph-theoretical optimization problems
related to integer programming, and applications of integer
The structure of this volume is much the same as that of the
previous ones. In Part 1 the publications are listed alphabetically
by the first author together with a reference code allowing the
user to identify them. Part 2 is a subject classification with 50 main
subject headings. Part 3 is an alphabetical catalogue of all
authors. The period from mid-1981 to autumn 1984 is covered.
There are 4751 new publications by 3690 authors.
The first three volumes have already proven to be very useful
for anyone working in this field, and it is without any doubt that
this fourth volume will continue to serve as an easy-to-handle and
comprehensive survey of all publications appearing in the field of
Linear and Nonlinear Programming
By David G. Luenberger
Addison Wesley, Amsterdam, 1984
This is a second edition of the popular book first published in
1973 and notable for being well written and clearly explained. It is
divided into 3 parts.
Part 1 is a self-contained introduction to Linear Programming,
including chapters of Basic Properties, The Simplex Method,
Duality, and Transportation and Network Flow Problems. Part II
covers optimality conditions and algorithms for Unconstrained
Optimization and includes chapters on Basic Properties, Descent
Methods, Conjugate Direction Methods and Quasi-Newton
Methods. Part III extends these ideas to cover Constrained
Optimization, with chapters on Optimality Conditions, Primal
Methods, Penalty and Barrier Methods, Dual and Cutting Plane
Methods, and Lagrange Methods. There are appendices
covering various aspects of mathematical notation, convex
analysis and linear algebra. Each chapter is augmented by
exercises which both illustrate and extend the material in the text
and also by a brief literature survey of relevant references. The
book is in hard cover and is very well produced and set out. Bold
face is used for vector notation.
The material that has been newly introduced in the second
edition includes the section on transportation and network flow in
Part 1. In Part III many of the important developments in
nonlinear programming over the last ten years have been
incorporated into several new sections and a new chapter on
Lagrange methods. Finally, more explanation and applications
exercises have been added to various parts of the book.
The chapter of Transportation and Network Flow is a
welcome addition to Part I which now provides a conventional b '
wide-ranging treatment of linear programming. My mal
criticism of this section is that degeneracy is almost entirely
neglected, apart from an exercise on Bland's rules, which will
tend to perpetuate the point of view that degeneracy is
unimportant in practice misguided in my opinion. Nothing is
mentioned of recent developments in ellipsoid algorithms.
Part II of the book shows its age in that it was largely
conceived in the "DFP era" before the BFGS method attained its
current pre-eminence. The merits of the BFGS method are not
sufficiently stressed, and the advantages of self-scaling methods
are over stated. Nothing is said about developments in trust
region methods, apart from a brief mention of the Levenberg-
Marquardt method. The book also lacks any treatment of the
practically important subject of nonlinear least squares and the
Part III has now become something of a hotch-potch of
numerous methods, new and old, for solving nonlinear
programming problems. Perhaps this is inevitable in view of the
uncertain state of the art in this area. The book does say
something about important new subjects such as 11 exact penalty
functions and sequential quadratic programming. However, I feel
that the treatment of quadratic programming itself is unduly
brief. Other subjects whose absence I noted included geometric
programming, integer programming and any general treatment
of nonsmooth optimization.
Overall however, I am sure that the book will continue to sr
well and provide a useful basis for student courses at va.rioG

Topics on Perfect Graphs
By C. Berge and V. Chvatal
North-Holland, Amsterdam, 1984
This book, published in 1984, on the 25th anniversary of
perfect graphs, presents selected results on this topic in a single
volume. These are reprints of classical papers on this subject as
well as surveys and new results.
The editors divided the whole volume into several parts
according to different points of view or techniques polyhedrall
methods, optimization, purely graph theoretical approaches, etc.)
rather than ordering the various contributions chronologically.
Therefore, this book does not provide much insight into how the
field developed over the years (one can find a brief sketch of the
history of perfect graphs in the Introduction), but it does provide
m,! quite complete survey of the important body of work stimulated
by the perfect graph conjecture, leading up to the frontiers of

lectures delivered at the tenth British Combinatorial Conference
held in Glasgow from July 22 26, 1985. The incredible speed at
which they were made available in book form is a tribute to the
efficiency of the publisher and (one suspects) to the ruthless
driving power of the editor. Perhaps this explains why one of the
nine lectures was not included.
The eight that made it in time make agreeable reading. The
OPTIMA public will probably derive most pleasure from the
contributions of G.R. Grimmett on various probabilistic models
for network and electrical flow, of A.J. Hoffman on greedy
algorithms that find the optimal solution, and of N. Robertson
and P.D. Seymour who survey their work on graph minors
including their impressive algorithmic results on the disjoint
fC'onnecting paths problem. In addition, G. Andrews discusses a
ew approach to a class of q-series originally studied by
Ramanujan; J. Beck (who recently received the Fulkerson Prize)
describes some of his beautiful work on the relations between
measure theoretic and combinatorial discrepancy theory; H.J.
Beker reviews adaptive algorithms for communication; J.H van
Lint discusses three open problems from coding theory and
C.St.J.A. Nash-Williams studies existence results for
detachments of graphs.
How useful are proceedings such as these? If at all, then only
if they are produced as quickly as these have been. All the
interesting new results contained here will surely find their way
into the regular journals. Undoubtedly, these journals would also
be delighted to publish authoritative surveys written by experts
such as those assembled on this occasion. So, unless proceedings
are set up to function completely like an introductory textbook,
they serve a very temporary purpose. With that in mind, we can
be grateful to lan Anderson for granting us this quick peek
behind the scenes of some very interesting current research.

Mathematical Programming with Data
Edited by A.V. Fiacco
Dekker, New York, 1982
The articles in these two volumes are based on papers
presented at the first Symposium on Mathematical Programming
with Data Perturbations. This symposium was held May 24 25,
1979, at the George Washington University and organized by A.V.
Fiacco and S.M. Robinson. The field of mathematical
optimization with data perturbations (also called parametric
optimization) has an increased importance for many topics (e.g.
stochastic optimization, multiobjective optimization, solution
procedures of nonlinear optimization, duality theory, ill-posed
optimization problems, model-building, approximation theory).
Furthermore, the theoretical and numerical results in parametric
optimization are often helpful for solving real-life practical
The reader will find a wide range of important and deep basic
results and applications in both volumes which can be
recommended to mathematicians who are in basic research
and/or applications in mathematical optimization.

Nominations for the
George B. Dantzig Prize being taken
This is a call for nominations for the George B.
Dantzig Prize which will be awarded at the annual
SIAM meeting in San Diego, July 18-22, 1988. The
prize is awarded for original work which, by its
breadth and scope, constitutes an outstanding
contribution to the field of mathematical pro-
gramming. The contributions eligible for
consideration are not restricted with respect to the
age or number of their authors, although preference
should be given to the singly-authored work of
"younger" people. The nomination for the award
will be presented by the Prize Committee (Olvi L.
Mangasarian, Chairman, George L. Nemhauser,
Katta G. Murty and Margaret H. Wright) to the
Executive Committees of the SIAM Council and of
the Mathematical Programming Society. Past
recipients of the George B. Dantzig Prize have been:
M.J.D. Powell and R.T. Rockafellar in 1982 and E.L.
Johnson and M.W. Padberg in 1985.
Please send your nominations by May 15, 1987 to
Olvi L. Mangasarian, Computer Sciences Depart-
ment, University of Wisconsin, 1210 West Dayton
Street, Madison, Wisconsin 53706, U.S.A.
