Linear programming.

In mathematical optimization, Dantzig's simplex algorithm (or simplex method) is a popular algorithm for linear programming.. The name of the algorithm is derived from the concept of a simplex and was suggested by T. S. Motzkin. Simplices are not actually used in the method, but one interpretation of it is that it operates on simplicial cones, and these …
