This quantity is devoted to Paul Erdos, who has profoundly encouraged arithmetic during this century, with over 1200 papers on quantity conception, advanced research, likelihood conception, geometry, interpretation conception, algebra set thought and combinatorics. considered one of Erdos' hallmarks is the host of stimulating difficulties and conjectures, to a lot of which he has connected financial costs, in keeping with their notoriety. A characteristic of this quantity is a set of a few fifty striking unsolved difficulties, including their "values."

The problem of how to take into account constraints in a direct search has also been investigated by Klingman and Himmelblau (1964) and Glass and Cooper (1965). The resulting methods, to a greater or lesser extent, transform the original problem. They have nowadays been superseded by the general penalty function methods. Automatic \optimizators" for on-line optimization of chemical processes, which once were well known under the names Opcon ( Bernard and Sonderquist, 1959) and Optimat (Weiss, Archer, and Burt, 1961), also apply modi ed versions of the direct search method.

Proceeding sequentially brought considerable advantages in the one dimensional case if it could only be assumed that the objective function was unimodal. Krolak and Cooper (1963) (see also Krolak, 1968) and Sugie (1964) have given an extension to several dimensions of the Fibonacci search scheme. For n = 2, two points are chosen on one of the two coordinate axes within the given interval in the same way as for the usual one dimensional Fibonacci search. The values of this variable are rst held constant while two complete Fibonacci searches are made to nd the relative optima with respect to Multidimensional Strategies 39 the second variable.

Failures must accordingly be planned for, if something can also be \learned" from them. This trial character of search strategies has earned them the name of trial-and-error methods. The most important of them that are still in current use will be presented in the following chapters. Their attraction lies not in theoretical proofs of convergence and rates of convergence, but in their simplicity and the fact that they have proved themselves in practice. In the case of convex or quadratic unimodal objective functions, however, they are generally inferior to the rst and second order strategies to be described later.
