SAS/OR 12.3 is largely
a maintenance release of SAS/OR software that runs on SAS 9.4. The
most significant addition is PROC OPTLSO for parallel hybrid local
search optimization. This procedure, formerly named PROC HPLSO, previously
was included only in SAS High-Performance Optimization but is now
available with SAS/OR for use in single-machine mode.
