# Thread: Simplex algorithm, working backwards, help asap!

1. ## Simplex algorithm, working backwards, help asap!

The problem is implementing the simplex algorithm. I am given the final tableau and need to work backwards to find the original coefficients of the optimal objective value. In other words, I am given ONLY a final, optimal tableau and need to somehow get from it the optimal objective function (ie, the function that I need to maximize)

Thank you for any help.

2. Most of the time the answer is not unique since the optimal solution is usually a vertex of the simplex in the solution space and you can have infinitely many hyperplanes which admits extrema at that point. The only time that the answer could be unique is that the hyperplane the objective function make happens to be parallel to one of the face of the simplex, and the answer you produce is in the strict interior of that face (if it's vertex, or somewhere on the edge, then still infinite possible objective functions)
