Webbsimplex criterion rule -of linear programming and the term C B B 1a - c , is called the reduced cost. If there are no variables with negative values of C B B-1a - c , then the solution cannot be improved on and is optimal. However, if a variable is identified by this rule then it should be entered into the basis.
