Mobile application to solve Linear Programming models with mixed variables (normal, integer, binary) using the "Simplex Method (big M)" and the "Branch and Bound Method". Many optimization problems require an integer variable solution. The main features are: - Assignment of names to decision variables - Up to 12 decision variables - Up to 12 constraints - Friendly user interface - Algorithm configuration - Dark mode - Save one model - 7 examples incluided - Internet connection required
