SAS^® Optimization

SAS Optimization 8.5 provides improvements to its mathematical optimization procedures, solvers, algorithms, and CAS actions, including the following enhancements:

• The LP, MILP, and NLP solvers make performance improvements.
• The MILP solver adds irreducible infeasible set (IIS) analysis.
• The NLP solver changes its default algorithm and makes three other updates.
• The runOptmodel action adds support for distributed COFOR loop execution, SUBMIT blocks, and BY-group processing.
• The LSO solver is renamed the black-box solver.
• The new solveBlackbox action calls the black-box solver.
• The cycle detection algorithm adds the ability to output the sequence of links in a cycle.
• The minimum cut algorithm enables you to specify the pair of nodes the cut must separate.
• The linear assignment problem algorithm adds a time limit option.
