Formula: In the Dual Simplex Method, feasibility is determined by checking if any of the coefficients in the current solution are negative.

Introduction to Dual Method Feasibility Check

The dual simplex method is an optimization algorithm used to solve linear programming problems. After each iteration, a feasibility check is required to determine if the current solution is valid. A feasible solution must not have negative coefficients; if any coefficient is negative, the solution is not feasible.

Parameter usage:


Data validation

Parameters must be numeric and properly formatted; otherwise, an error message is returned.


This check is critical in the dual simplex method for determining whether the current solution is a candidate for the optimal solution in a linear programming problem.
