Subject: | [Help-glpk] 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.
