3. Proposed method
3.1. The method solving ILP with revised B&B procedure
many researchers have a great deal to solve ILP problem for four decades 6 some of are and some are too complicated for business use. Compared with many others, B&B pro- cedure which uses the enumerative divide-and-conquer technique is a better method. Besides, B&B has already been in common use now. However, it might require an enormous amount of computation sometimes when solving large-scale ILP problems. Although there are heuristics for enhancing the ability of B&B by guessing which branch could lead to a quick solution, there is no solid theory that will always yield consistent results Hence, in this section, we propose a revise method to IPL Our method to cutoriginal the space many subspaces using objective function before implementing It could narrow down feasible solution range. After labeling these subspaces based on the"distance" from objective function, we can apply upon subspaces one by one. The nearest subspace will be the first one to be searched The first optimum solution we get in the nearest sub is promised to be the optimum solution in all solution space because of using objective function. The procedure of our proposed is explained below
