I'm trying to write a program to solve diet problem http://www.phpsimplex.com/en/diet_problem.htm
using SIMPLEX algorithms. My assignment require also to calculate the efficiency of the algorithms.
I understood from wiki http://en.wikipedia.org/wiki/Simplex_algorithm that it's has exponential time in worst case. But it doesn't show the exact big O notation, or how I could calculate that.
Is there any advice how could I calculate the efficiency of Simplex algorithm for the above diet problem?
