The big M method

The big M method. LI Xiao-lei. The big M method. The simplex algorithm requires a starting bfs. We found a starting bfs by using the slack variables as our basic variables. If an LP has any ? or equality constraints, a starting bfs may not be readily apparent.

LINEAR PROGRAMMING

LINEAR PROGRAMMING. SIMPLEX METHOD. Introduction. With only two decision variables it is possible to use graphical methods to solve LP problems But most real life LP problems are too complex for simple graphical procedures We need a more powerful procedure called the simplex method
