### Linear programming general question

Posted:

**Mon Mar 06, 2017 3:38 pm**If one LP-problem has more than one optimal solution, how do i find the rest optimal solutions? I've found the first one, but I cannot find the remaining ones, as there's no variable that I can increase anymore on the objective function. Also the exercises shows that it has 3 optimal solutions, but I've only found the first one by the simplex method.
