What is degeneracy? • As you know, the simplex algorithm starts at a corner point and moves to an adjacent corner point by increasing the value of a non-basic

An LP is degenerate if in a basic feasible solution, one of the basic variables takes on a zero value Degeneracy is a problem in practice, because it makes the

Degeneracy in linear programming problems has been extensively studied since it To every feasible solution X there corresponds a bipartite graph Gx defined as Since the solution is infeasible at least one basic variable is negative, say (il
