George Bernard DantzigGeorge Bernard DantzigDantzig is known for his development of the simplex algorithm, an algorithm for solving linear programming problems, and for his other work with linear programming. In statistics, Dantzig solved two open problems in statistical theory, which he had mistaken for homework after arriving late to a lecture by Jerzy Neyman.https://en.wikipedia.org › wiki › George_DantzigGeorge Dantzig – Wikipedia, professor emeritus of operations research and of computer science who devised the “simplex method” and invented linear programming (which is not related to computer programming), died May 13 at his Stanford home of complications from diabetes and cardiovascular disease. He was 90 years old.
In 1947 George Dantzig, a mathematical adviser for the U.S. Air Force, devised the simplex method to restrict the number of extreme points that have to be examined. The simplex method is one of the most useful and efficient algorithms ever invented, and it is still the standard method employed on computers to solve optimization problems.
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.

What is the idea of simplex method?
Simplex method is an approach to solving linear programming models by hand using slack variables, tableaus, and pivot variables as a means to finding the optimal solution of an optimization problem. Simplex tableau is used to perform row operations on the linear programming model as well as for checking optimality.

Simplex – Wikipedia
In geometry, a simplex (plural: simplexes or simplices) is a generalization of the notion of a triangle or tetrahedron to arbitrary dimensions.The simplex is so-named because it represents the simplest possible polytope made with line segments in any given dimension.. For example, a 0-simplex is a point,; a 1-simplex is a line segment,; a 2-simplex is a triangle,
