- In operations research, the big m method is a method of solving linear programming problems using the simplex algorithm the big m method extends the power of the simplex algorithm to problems that contain greater-than constraints.
- Complete example of the of the two phase method with 3 variables and 3 artificial slack variables iterations are performed until the solution becomes trivial at the end of the first phase, after replacing the original objective function to obtain the optimal solution.
- Very nice discussion, paul a couple of points on big m in the simplex method: - one reason you don't hear complaints is that almost nobody actually implements big m.
- Linear programming is an optimization technique for a system of linear constraints and a linear objective function big m simplex method this method is viable for any linear programming problem that does not match the forms of the previous section.
