Abstract
This paper describes a parallel branchβandβbound algorithm for general integer linear programming problems and its implementation on a distributed memory multiprocessor nCUBE2.
With a branchβandβbound algorithm, the amount of computation on each search tree node varies, and in general, is large. This has led to development of an effective communication strategy for the algorithm presented herein. Its implementation and performance evaluation also are described.
The results show that the more difficult the problem instances become in terms of time to solve on a sequential computer, the more efficient the algorithm presented here proves to be.
