Simplex method is an iterative procedure that allows to improve the solution at each step. This procedure is finished when isn't possible to improve the solution. Starting from a random vertex value of the objective function, Simplex method tries to find repeatedly another vertex value that improves the one you have before. how do you say semper fidelis
