Finding feasible solutions to a LP
basic feasible solution: put the slack variables on the left hand side How-ever this is not always the case especially for minimization problems or problems with equality constraints in the original model Consider the following simple LP minimize x s t x ≥ 5 x ≥ 0 Forget for a minute that the solution is obvious If we try to use simplex |
Can we limit our attention to basic feasible solutions when solving a linear program?
Later, we shall see that, when solving a linear program, we can restrict our attention to basic feasible solutions. The simplex method is an iterative method that generates a sequence of basic feasible solutions (corresponding to di erent bases) and eventually stops when it has found an optimal basic feasible solution.
