Simplex method with python
Webb23 sep. 2015 · The Simplex Method (developed by George Dantzig in 1946) is the earliest solution algorithm for solving LP problems. It is an efficient implementation of solving a series of systems of linear equations. By using a greedy strategy while jumping from a feasible vertex of the next adjacent vertex, the algorithm terminates at an optimal solution.
