WebbThe simplex method is a mathematical technique used in materials, manufacturing, and industrial engineering. The simplex method is a way to find the minimum material cost for producing a product. It is based on the assumption that production can be done with materials with different properties, and each material has an associated unit cost.

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. The name of the algorithm is derived from the concept of a simplex and was suggested by Visa mer George Dantzig worked on planning methods for the US Army Air Force during World War II using a desk calculator. During 1946 his colleague challenged him to mechanize the planning process to distract him from taking another job.
