This is a small demo application to illustrate how to use CMPL with an application-generated model file.
This application implements the popular Mastermind board game. The game will first create the "code" consisting of four "colors" (which are 1 to 6 in this implementation) and then allow for guesses. Each guess also consists of four colors. If the guessed color is at the right position, the result for the guess will contain a black pin. If the guessed color is part of the "code" but not at the correct position the guess result will contain a white pin. If the "code" does not contain the guessed color no pin will be output.
Using the guess output from the Mastermind board, the application auto-generates a CMPL model. This is then solved using the CMPL CBC solver to generate the next guess. From my tests, the solver has always been able to guess the correct solution within the maximum allowed 12 tries.
Make sure the application can write to the etc subdirectory of the application directory. It needs to store generated CMPL files there to pass to the CMPL CBC solver in order to get a new guess.
Install the CMPL package on your machine and make sure it is in the path.
Compile and run the application.
