New Orchard-Hays Prize
to be awarded in Boston
William Orchard-Hays has been a leader in the
development of mathematical programming
software since the original development of a
Simplex code for the IBM 701 at the RAND
Corp. in the early 1950's.
At the XII International Symposium
on Mathematical Programming in Boston,
Massachusetts, in August, 1985, The Mathe-
matical Programming Society will confer for
the first time the Orchard-Hays Prize for
Excellence in Computational Mathematical
Programming. The prize for 1985 consists of
$500, travel expenses to attend the meeting,
and a commemorative plaque.
Topics covered by the term "computa-
tional mathematical programming" include
new computational methods in the field of
mathematical programming together with
experimental evidence of their effectiveness,
development of methodology for testing
mathematical programming software, pro-
cedures for improving the efficiency and
accuracy of existing algorithms, and pro-
cedures for analyzing large-scale mathe-
matical programming models.
Through the awarding of this prize,
the Committee on Algorithms (COAL)
together with the MPS Council has found an
appropriate vehicle for rewarding and
recognizing excellence in an important
aspect of our field: computation. The
screening of books and papers for the 1985
Orchard-Hays prize will be carried out by
a committee chaired by Professor George
Dantzig. This prize is funded by industry

1984. The registrations show that a large
percentage of participants are practitioners
who need optimization algorithms as a tool
in their application models, e.g. in mech-
anical engineering or operations research.
I i- main motivation is to learn new
solution methods for solving optimization
problems. In particular, they are very much
interested in obtaining some information
about corresponding computer programs.

ware fair in the sense that information
material about i .1 I -''i. optimization codes
is to be displayed during the ASI and ques-
tionnaires are to be published in the confer-
ence proceedings. We all know that it is
quite difficult to distribute software infor-
mation to possible users, and COAL offers
the chance for making some advertising for
mathematical programming codes.

Optimization and Nonsmooth Analysis
By Frank H. Clarke
John Wiley, New York 1983, 308 p,
During the last decade considerable progress was made in the
analysis of nonsmooth problems, especially in optimization. One of the
basic techniques applied in this field is the use of various kinds of gener-
alized derivatives. A broadly used variant among these consists of Clarke's
11 -...1 pi i.i, r,~ ', developed in the early 1970's and now presented in
Chapter 1 is devoted to an explanation and overview of the book's
contents and provides an introductory exposition of the main concepts.
Here and elsewhere the reader finds examples drawn from economics, engi-
neering, mathematical physics, and various branches of analysis. Chapter 2
deals with the calculus of the generalized gradient and relates it to the
associated geometric concepts of normal and tangent cones. In Chapter 3
the foundations are laid for the Ii; r;. i to follow. The author con-
siders the problem of minimizing a function over the set of trajectories of a
differential inclusion subject to certain constraints and gives necessary and
sufficient conditions for optimality. This theory is applied to furnish a
nonsmooth calculus of variations (Chapter 4) and nonsmooth optimal
control (Chapter 5). Chapter 6 deals with optimization theory in general.
It contains sections on Lagrange multipliers, on different types of con-
straint qualifications, and on sensitivity of nonsmooth problems. The
concluding Chapter 7 presents mixed applications in analysis. These range
from generalized versions of some classical theorems-like the inverse
function theorem-over fixed points of continuous maps, to certain exis-
tence results on hamiltonian dynamical systems. Here the techniques
developed in Chapters 2 and 3 lead not only to new results, but (as in
Chapters 4 and 5) shed new light on classical ones by allowing for novel
Written in a lucid style, Clarke's book may well serve as an introduc-
tion into nonsmooth analysis for the non-expert, but equally well (in spite
of not being encyclopedic in scope) as a reference work for those in any of
the various fields that use optimization.

Polynomials and Linear Control Systems
by Stephen Barnett
New York, Basel 1983
This book treats two major problems related to polynomials:
the problem of determining the greatest common divisor of two poly-
nomials and the problem of checking the stability of a single polynomial.
Although there is already vast literature on the subject, this book takes
another look at these problems and, more specifically, tries to rederive
known results using techniques that are more familiar to control engineers.
In the first section, for example, the condition for the existence of a
(greatest) common divisor between two polynomials is derived via com-
panion forms first and is then linked to other tests such as Sylvester and
Bezout forms and tabular arrays (Routh) based on euclidean type recur-
In the second section, the connections with control theory are
carried through by linking these tests to the controllability of a system in
companion form. Along the same line, control problems such as canonical
forms and pole-placement via feedback are discussed.
The third section is probably the most interesting one. Here, the
author again uses classical algebraic tools of control theory (namely the
Lyapunov equations as stability test) to derive known stability and root
location criteria both for the continuous- and discrete-time case. These are
the criteria of Routh, Hurwitz, Lienard-Chipart, Hermite for the contin-
uous-time case and of Jury-Marden, Schur-Cohn and Schur-Cohn-Fujiwara
for the discrete-time case. Finally, links are also made with the Sturm
sequences and the Cauchy index, which is the more classical approach for
discussing the above criteria.
The fourth section is devoted to extending the above results to
polynomial matrices, with special emphasis on their use for multivariable
systems such as polymial matrix fraction descriptions and feedback.
Although the results are much scarcer here, an account is given of some
recent results about greatest common divisors using ideas developed in the
The last section is devoted to generalized polynomials or poly-
nomials written in terms of other (for instance othogonal) polynomials.
Here again, extensions of some of the results of the previous sections are
The book is clearly written for control engineers since concepts
familiar to them are used to tackle the problems. The term "control
systems" appearing in the title is also justified by the several examples and
applications of the two basic problems mentioned above, which are largely
extracted from the control area. Yet one should not expect too much
from the "control systems" part of the book. The style, liri. .1 kept
very simple, as well as the examples, are still of a rather algebraic (theoret-
ical) nature than what would be expected by "control engineers". Guide-
lines for choosing and implementing some of these criteria or methods are
also too scarce to make it appealing to control engineers. The book is
therefore rather meant for what could be called mathematicall control
engineers". Finally, it is worth mentioning that the book contains over
400 references and is therefore a welcome guide in the wealth of (recent)
papers in the area.

Descartes on Polyhedra, A Study of the De Solidorum Elementis
by P. J. Federico
Springer, Berlin, 1982
The book is a -,.. I, treatment of the history and the content of
a manuscript of Descartes on polyhedra ("De Solidorum Elementis"). This
manuscript is only known as a copy, made by Leibniz, and it was found as
late as 1860, approximately 230 years after it had been written. The
manuscript contains a formula of which the Euler formula for polyhedra is
an immediate consequence. There are numerous contradictory statements
by various authors concerning the priority of Descartes or Euler for this
formula, and this was the author's main motivation for writing the book.
It is divided into three main chapters. The first discusses the (very
interesting) history of the manuscript itself; the second chapter treats the
parts of manuscript dealing with geometric properties of (3-dimensional)
convex polyhedra; and the third concerns those parts which deal with
figurate numbers associated with polyhedra (especially the regular and
The second chapter is certainly the most ini..- r;l .a as it deals with
the part of the manuscript which contains the most significant results
judged from the modern point of view.
The author's clear translation of the Latin text is followed by
detailed comments on the mathematical content. The main results of
Descartes are subsumed by the author in six Propositions. Except for
Proposition 4 (which is an algebraic treatment of the number of regular
convex polyhedra) all of them concern relations between different kinds of
angles and numbers of faces of 3-polyhedra. Proposition 1 states that the
sum of the exterior solid angles is equal to eight right solid angles (unfor-
tunately, Figure 4(b), which is meant to illustrate the planar analogue of
this fact, is false and ..- .. This result, though it can be interpreted
as a consequence of the GaupBonnet Theorem or of the Steiner-formula
for parallel convex bodies, seems not t have been explicitly known before
the discovery of the Descartes manuscri t.
Proposition 6 states: P = 2F +2V 4 where P is the number of
plane angles (angles at vertices of facet F the number of facets and V
the number of vertices of a polytope. As another statement of the manu-
script is P = 2E, where E is the number of edges, it has been asserted by
many authors that Descartes actually was aware of Euler's Theorem which

by this identity is equivalent to Proposition 6. The author is right in saying
that this question can only be answered: "Yes, probably" or "No, prob-
ably", and he discusses this in a very detailed way (including the literature
on this question). The only thing that one can be safe about is that
Descartes, in case he did see the identity E = F + V 2, certainly did not
think it was as ;..'. .-' as his Proposition 6.
The Descartes manuscript certainly represents the "state of the art"
in the theory of convex polyhedra for 1630. Its content, its spirit and its
historic meaning are carefully elaborated in this book which was a pleasure
to read. I recommend it to everybody interested in the history of poly-
