In this lecture, we given an overview of this central topic in operations research and describe its relationship to algorithms that we have considered. The simplex algorithm applies this insight by walking along edges of the polytope to extreme points with greater and greater objective values. This continues until the maximum value is reached, or an unbounded edge is visited (concluding that the problem has no solution). Visa mer In mathematical optimization, Dantzig's simplex algorithm (or simplex method) is a popular algorithm for linear programming.
