Subject:  [Helpglpk] about dual value 
Date:  Fri, 12 Jun 2009 17:07:13 +0300 
Hello I use glpk to solve a MIP problem : min c1 * x + c2 * y A1 * x + A2 * y <= b (x is a vector of integer, y is a vector of real value) After having solved the mip problem succefully (optimal solution : x = x' and y = y'), I want to have the dual value of b with relaxing problem to continuous one and keep the solution at (x', y'). Is there a function if GLPK giving this informaion? Or someone can help me to calculate these values. Many thanks. CEN Beyond Hotmail  see what else you can do with Windows Live. Find out more.
