Simplex Method Example

It's a function that finds the minimum value of a two variables objective function with a deterministic zero order algorithm: simplex method. The input variables are:-fun: inline function of the objective function-init_point: initial point for the simplex method-step_size: initial dimension of...

This function is able to detect almost all types of properties/characteristics present in an LPP such as unbounded solution, alternate optima, degenaracy/cycling and infeasibilty. It only fails to work when there are redundant constraints present in the problem. However, it is rare and can be...

Simplex-in-PHP are PHP scripts that solve small linear programming and integer linear programming problems executing the simplex method step by step, printing the tableau and drawing the graphical analysis.Useful for students in Operational Research.

This is a single M-file that implements a Nelder-Mead simplex minimizer. It makes use of MATLAB's persistent variables to create a "state machine" implementation. This allows entire minimization programs to be written as MATLAB scripts, as it does not require a function to be defined and passed...
