WebbIn fact, in 1947, G.B. Dantzig conceived the Simplex Method to solve military planning problems asked by the US Air Force that were written as a linear programme, that is a system of linear equations. In this course, we introduce the basic concepts of linear programming. We then present the Simplex Method, following the book of V. Chv´atal [2]. WebbCutting Plane Method Introduction Method of Integer Forms for IP Mixed cut for MILP Row generation for the TSP 5.3 The basic idea of the cutting plane method is to cut off parts of the feasible region of the LP relaxation, so that the optimal integer solution becomes an extreme point and therefore can be found by the simplex method.

WebbThe simplex method is an iterative process for finding an optimal basic feasible solution to a standard linear program. It starts at some BFS and in each step moves to an adjacent one with a higher objective value. The following picture shows one possible run of the simplex method for the linear program (1.2).
