WebbExample of an infeasible LP As we mention above, not all LPs are feasible: sometimes the constraints are just impossible to satisfy simultaneously. In that case, the Simplex Method discovers this in Phase 1. For example, consider the following LP: Maximize x 1 − x 2 + x 3 WebbAs a simple example, you could add a new "slack" variable on each capacity constraint, having a very high penalty cost. Then infeasibilities in your capacities would be signalled by positive values for these slacks at the optimal solution, rather than by a mysterious lack of feasibility in the linear program as a whole. http://www.universalteacherpublications.com/univ/ebooks/or/Ch3/splcase1.htm dutch oven bread over fire

The simplex solution approach relies on choosing an initial B matrix, and then interactively making improvements. Thus, we need to identify how the solution changes when we change the B matrix. First, let us look at how the basic solution variable values change.
