The purpose of this note is to report computational experience additional to that recently summarized by Gue et al., with two algorithms for the zero-one linear programming problem. An error in Gue's paper is corrected. The utility of one of the algorithms as a suboptimizer is indicated. [ABSTRACT FROM AUTHOR]

A brief history of integer and continuous nonlinear programming is presented as well as the current obstacles to practical use of these mathematical programming techniques It is forecast that the useful contributions to nonlinear programming actualls made in the next few years are more likely to he consolidations than theoretical breakthroughs These contributions are likely to be the documentation of standard test problems, construction of user oriented software, and comparisons of currently known algorithms to demonstrate which techniques are best for specific problems.

A computer language and a set of programs within that language are described which allow the formulating and solving of a class of space planning problems. The language is an extension of Algol and includes means to represent spaces and objects, to manipulate them, and to test the resulting arrangements according to a variety of constraints. The algorithms used to solve problems expressed in this language rely on heuristic programming. Both the language and the search algorithms are detailed. [ABSTRACT FROM AUTHOR]
