Optimizing a Constraint: Reconstructing an Integer Programming Constraint More Simply

Features Demonstrated

The following features are demonstrated in this example:

  • problem type: linear programming

  • CLP procedure

  • set operator UNION

  • IMPVAR statement

  • ABS function

  • reading multiple data sets

  • multiple objectives

  • SOLVE WITH CLP

  • CLP solver option FINDALLSOLNS

  • multiple solutions

  • predeclared numeric parameter _NSOL_

  • using the .lb and .ub constraint suffixes to modify the right-hand side of a constraint

  • CONSTANT function

  • PROBLEM and USE PROBLEM statements
