Simplex method is used for
WebbEvery book on linear optimization explains the simplex method as a two-stage algorithm: the first for finding a feasible corner as a starting point, and the second for finding the optimum. The first uses a dual problem. Take a look at D. Bertsimas and J. N. Tsitsiklis: "Introduction to linear optimization", for example. Webb26 juni 2024 · i want to use the simplex-algorithm in matlab to solve my optimization problem. After reading the threads i underestand that the simplex-algorithm is not used for linprog, instead the dual-simplex is the default solution which essentially performs a simplex algorithm on the dual problem.
