The pseudo-objective function evaluates to 3.1e-12 which exceeds the required tolerance of 1e-12 for a solution to be considered 'close enough' to zero to be a basic solution. Consider increasing the tolerance to be greater than 3.1e-12. WebbThe simplex algorithm is an iterative algorithm to solve linear programs of the form (2) by walking from vertex to vertex, along the edges of this polytope, until arriving at a vertex which maximizes the objective function c x. To illustrate the simplex method, for concreteness we will consider the following linear program. maximize 2x 1+ 3x 2
