Implementation of Simplex Algorithm and Branch & Bound Algorithm

Simplex Algorithm in MATLAB

Implementation of Simplex algorithm with Lexicographical minimum ratio test and Intiger pivoting for minimization. Solves linear problems of the form LP>=

Inputs:
A: m x n matrix of inequalities (>=)
a: m x 1 right hand side
c: optimization function

Outputs:
x: best feasible solution
cx: cost of the solution due to c
y: solution of the dual problem
