WebbThe answer is easy. They both (simplex and interior point methods) are a mature field from an algorithmic point of view. They both work very well in practice. The good reputation of I.P.M. (interior point methods) is due to its polynomial complexity in the worst case. That is not the case for simplex which has combinatorial complexity.
