Product description

Dual simplex method. C# sources. Dual simplex method. C# sources. Dual simplex method. C# sources.

A program for solving linear programming problems by the dual simplex method. Sources in Microsoft Visual C# with detailed comments.

The program itself constitutes a dual task and brings it to the canonical form. Displays a detailed report on the progress of the task. It is possible to solve both dual and direct problems, and quickly switch between them for a more detailed analysis and study of the problem.
There are three problem solving modes:

1) Automatic
2) Step by step
3) Manual

In the first mode, the program itself chooses the resolving column and row, which provide the maximum increase or decrease in the objective function. It also automatically recalculates all tables.

In step mode, each recalculated table is displayed. This mode is convenient for viewing intermediate results of solving a problem. The allowing column and line, in this mode, the program also chooses itself.

In manual mode, the user selects the permissive row and column.
