Highlights of Enhancements in SAS/OR 12.1

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)
