Associated with every LP problem, there is another dual LP problem, which involves a different set of vari ables and constraints but shares the same optimum results. The original LP problem referred as the primal one can be converted into its corresponding dual problem. The principal ideas and results have origins in the work of John von Neumann(13]. Based on the dual theorem, the primal and dual problems have equal optimum a objective function values(if the problem has optimum solutions. For example as follows, if the primal is LP problem searching for maximum solution with n variables and m constraints, then the dual problem will be another LP problem searching for minimum solution with m variables and n constraints 18). Consider the primal problem
