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. Webb23 nov. 2015 · This is correct. For the leaving variable, you must choose one that minimizes the ratio { b i / a i j a i j > 0 }, where b i is the right hand term of constraint i, and a i j is the element at line i, column j, where j is the column of your entering variable. So in your case, if your entering variable is x 1, you have to choose the minimizer ...
