Abstract : An algorithm for the classical setcovering problem with additional base constraints is presented. The base constrained set covering problem is: Minimize cx, subject to Ex > or = B, (x sub j) = 0 or 1 (j = 1,...,n), and Bx < or = 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 zeroone single branch enumeration with linear programming and other feasibility criteria. A heuristic is used which sometimes finds an initial solution to the base constrained setcovering problem. Computational results are given. (Author)
