Jun 13,  · Phase 1 of the two-phase simplex algorithm tries to find a basic feasible solution. Artificial variables are introduced in phase 1 and dropped at the beginning of phase 2. If the constraints are feasible, then the basic feasible solution obtained at the end of phase 1 is used in phase 2 to begin a search for the optimal solution (which lies at. Simplex on line Calculator is a on line Calculator utility for the Simplex algorithm and the two-phase method, enter the cost vector, the matrix of constraints and the objective function, execute to get the output of the simplex algorithm in linar programming minimization or maximization problems. This problem (Phase I) has an initial basic feasible solution with basic variables being x4, x7 and x 8. If the minimum value of x 7 + x 8 is 0, then both x 7 and x 8 are 0.
