Dantzig realized that one of the unsolved problems that he had mistaken as homework in his professor Jerzy Neyman's class (and actually later solved), was applicable to finding an algorithm for linear programs.

First, for each variable with a lower bound other than 0, a new variable is introduced representing the difference between the variable and bound.

The original variable can then be eliminated by substitution.

The algorithm always terminates because the number of vertices in the polytope is finite; moreover since we jump between vertices always in the same direction (that of the objective function), we hope that the number of vertices visited will be small.

The solution of a linear program is accomplished in two steps.

Dantzig's core insight was to realize that most such ground rules can be translated into a linear objective function that needs to be maximized.

After Dantzig included an objective function as part of his formulation during mid-1947, the problem was mathematically more tractable.

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.

Dantzig later published his "homework" as a thesis to earn his doctorate.

The column geometry used in this thesis gave Dantzig insight that made him believe that the Simplex method would be very efficient.
