This paper is concerned with a new linearization strategy for a class of zero-one mixed integer programming problems that contains quadratic cross-product terms between continuous and binary variables ...

In this paper we discuss some branch and bound methods implemented in the UMPIRE mathematical programming system for solving practical integer programming problems and give details of computational ...

To continue with the solution of this problem, invoke PROC LP with the ACTIVEIN= and PRIMALIN= options and reset the IMAXIT= option. This restores the branch and bound tree and simplifies calculating ...
