Features Demonstrated

The following features are demonstrated in this example:

  • problem type: mixed integer linear programming

  • sets of tuples

  • sets indexed by other sets

  • reading multiple input data sets

  • set operators UNION, INTER, and CROSS

  • CARD function

  • using a colon (:) to select members of a set

  • modeling if-then constraints by using binary variables

  • FILE statement

  • PUT statement
