Highlights of the SAS/OR enhancements include the following:
multithreading is used to improve performance in these three areas:
PROC OPTMODEL problem generation
multistart for nonlinear optimization
option tuning for mixed integer linear optimization
concurrent solve capability (experimental) for linear programming (LP) and nonlinear programming (NLP)
improvements to all simplex LP algorithms and mixed integer linear programming (MILP) solver
new decomposition (DECOMP) algorithm for LP and MILP
new option for controlling MILP cutting plane strategy
new conflict search capability for MILP solver
option tuning for PROC OPTMILP
new procedure, PROC OPTNET, for network optimization and analysis
new SUBMIT block for invoking SAS code within PROC OPTMODEL
SAS Simulation Studio improvements:
one-click connection of remote blocks in large models
autoscrolling for navigating large models
new search capability for block types and label content
alternative Experiment window configuration for large experiments
selective animation capability
new submodel component (experimental)
