 Criss-cross algorithm

The Criss-cross algorithm is a method used in linear programming to find optimal solutions for certain types of optimization problems, particularly in the context of solving systems of linear equations. The algorithm is especially useful when dealing with problems that involve transportation and assignment structures. ### Key Features of the Criss-cross Algorithm: 1. **Type of Problems**: It is primarily used for transportation problems, assignments, or linear programming problems that can be represented in a tabular format.
