Sub Main () ' In this QuickStart sample, we'll use the Mixed Integer ' programming capabilities to solve Sudoku puzzles. If some variables are restricted to be integer and some are not then the problem is a mixed integer programming problem.Thecase where the integer variables are restricted to be 0 or 1 comes up surprising often. Mixed integer linear programming (MILP) is a powerful representation often used to for-mulate decision-making problems under uncer-tainty. Mixed-integer nonlinear programming (MINLP) problems combine the difficulty of optimizing over discrete variable sets with the challenges of handling nonlinear functions. An integer programming problem in which all variables are required to be integer is called a pure integer pro-gramming problem. 225 - 243.Google Scholar We therefore turned to solving a (linear) Mixed Integer Program (using Gurobi, a powerful commercial solver).
