The simplex method
WebThe simplex algorithm is an iterative algorithm to solve linear programs of the form (2) by walking from vertex to vertex, along the edges of this polytope, until arriving at a vertex … WebWith the above ideas, we focus on the simplex method and study how it efficiently solves a linear program. Finally, we discuss some properties of unbounded and infeasible problems, which can help us identify whether a problem has optimal solution. 2-0: Opening. 4:39. 2-1: Introduction. 3:51.
