Several SAS/OR optimization solvers have improved their performance significantly from SAS/OR 13.1 to SAS/OR 13.2. The MILP solver is, on average, 75% faster in SAS/OR 13.2. For problems that require more than 1 second to solve, the MILP solver is 85% faster, and for problems that require more than 10 seconds to solve, it is 95% faster.
For the NLP solver, on average the active-set algorithm is 25% faster and the interior point algorithm is 12% faster in SAS/OR 13.2. For the LP solver, the interior point algorithm is 11% faster.
