Webbsimplex method, standard technique in linear programming for solving an optimization problem, typically one involving a function and several constraints expressed as inequalities. The inequalities define a polygonal region, and the solution is typically at one of the vertices. The simplex method is a systematic procedure for testing the vertices as … WebbSimplex Method: In more realistic problems, a solution may not be obvious, especially if there are many ingredients each having constraints. A simple procedure is needed to generate an optimal solution no matter how complex the problem.

Webbimization problem and we know how to use the simplex method to solve it. We need to write our initial simplex tableau. Since we have two constraints, we need to introduce the two slack variables u and v.
