    If all decision variables in a mathematical optimization problem are required to take integer values, the problem is classified as a pure integer programming problem. This is because every variable in the model is constrained to be an integer, without any exceptions.

    Explanation of the Options:

    1. Pure Integer Programming Problem: This applies when all decision variables are integers. For example, problems involving decisions like the number of items to produce, the number of trucks to use, or binary decisions (e.g., yes/no) fall into this category.

    2. Mixed-Integer Programming Problem: This applies when some variables are integers while others can take continuous (non-integer) values. For instance, a problem where the number of machines is an integer but the production rate is continuous would be mixed-integer programming.

    3. Simplex Method Problem: The simplex method is a technique used to solve linear programming problems where variables are not restricted to integer values. It is not directly applicable to integer programming problems unless combined with other methods like branch-and-bound.

    4. Gorksy Type Problem: This is not a recognized classification in mathematical optimization and does not apply here.

    What is a mixed integer programming problem?
    If some variables are restricted to be integer and some are not then the problem is a mixed integer programming problem. The case where the integer variables are restricted to be 0 or 1 comes up surprising often. Such problems are called pure (mixed) 0-1 programming problems or pure (mixed) binary integer programming problems.
