Abstract

An algorithm for the classical set-covering problem with additional "base" constraints is presented. The "base" constrained set covering problem is: Minimize cx, subject to Ex ≥ e, xj = 0 or 1 (j = 1,...,n), and Bx ≤ d. Here E is an m by n matrix of zeros and ones, e is an m column of ones, c and d are nonnegative vectors, and B is a nonnegative array having row diagonal structure. The algorithm is basically a zero-one single branch enumeration with linear programming and other feasibility criteria. A "heuristic" is used which sometimes finds an initial solution to the base constrained set-covering problem. Computational results are given.
