As we have discussed in previous articles, the Shadow Price of a constraint represents the rate of change of the optimal value as a result of a marginal change in the right-hand side of a constraint. “Marginal” is understood as a modification that does not change the geometry of the problem, that is to say, […]

## 10 Things You need to know about Simplex Method

The Simplex Method was developed by George Dantzing in 1947. It is without a doubt the most popular algorithm when it comes to solving a Linear Programming (LP) model, and it plays a major role in the introduction to Operations Research (OR). Today we’re presenting a summary of 10 main concepts about the use and […]

## Example of Infinite Solutions in the Simplex Method

One of the possibilities that we may face when solving a Linear Programming model through the Simplex Method is finding multiple or infinite solutions, this means there is a stretch of feasible solutions that report the same value for the objective function that cannot be improved. If after applying the necessary iterations of the Simplex Method […]
