If you try to solve these you will see that code doesn't have an answer and I want to know what exactly must change in order to work. If we nd an optimal solution to this linear program and its. ![]() %This is the one that don't give me any answerĪ=c(1:end-2,1:end-1) b=c(:,end) f=c(end-1,1:end-1) f1=c(end,1:end-1) Ī=c(1:end-1,1:end-1) b=c(:,end) f=c(end,1:end-1) x2R4 xa2R2 xa 1 + x a 2 subject to x 1 + 2x 2 + x 3 + x 4 + xa1 7 2x 1 + x 2 + x 3 + 3x 4 + xa2 1 x 1 x 2 x 3 x 4 x a 1 x a 2 0: The smallest conceivable value of xa 1 + xa2 in the optimal solution to this linear program is 0, and that can only be achieved if xa 1 xa2 0. Working Example and not Working Examples are in the picture below : If the minimum value of x7 x8 is 0, then both x7 and x8 are 0. ![]() The latter is the actual bare-bones algorithm it takes the problem data alongside an initial basic feasible solution and iterates until it fins an optimal solution or identifies the problem as unlimited. This problem (Phase I) has an initial basic feasible solution with basic variables being x4, x7 and x8. The former is a wrapper that does a bunch of error checking and then solves phase I and phase II of the simplex method by calling simplexcore. ![]() In some examples it's not working and I can't find what the problem is. Two-phase mthod: an algorithm tht soIves (P ) in tw phases, whre in Phase 1, we solve an auxiliary LP problem to either get a feasible basis or conclude that (P ) is infeasible. I have a problem with my MATLAB code that solves linear equations with two phase simplex method.
