      • setTableau

        void setTableau​(SimplexTableau tableau)
        Set the simplex tableau used during the optimization once a feasible solution has been found.
        Parameters:
        tableau - the simplex tableau containing a feasible solution

      • getSolution

        public PointValuePair getSolution()
        Retrieve the best solution found so far.

        Note: the returned solution may not be optimal, e.g. in case the optimizer did reach the iteration limits.

        Returns:
        the best solution found so far by the optimizer, or null if no feasible solution could be found

      • isSolutionOptimal

        public boolean isSolutionOptimal()
        Returns if the found solution is optimal.
        Returns:
        true if the solution is optimal, false otherwise
