WebbSimplex method is suitable for solving linear programming problems with a large number of variable. The method through an iterative process progressively approaches and … Webbrevised simplex method. The function should take as input the constraint matrix A, the right hand-side vector b, and the cost vector c, and output an optimal solution vector x and the optimal cost, or indicate that the LP is unbounded or infeasible. It should also output the number of simplex pivots or iterations used.
