SAS Optimization 8.2, a SAS Viya product, was released on December 12, 2017. SAS Optimization provides many of the same optimization capabilities as SAS/OR, but SAS Optimization also incorporates many distributed optimization features. SAS Optimization 8.2 adds several new capabilities:

The MILP, network, and NLP solvers and the decomposition algorithm (for LP and MILP) improve their performance.
The LP and MILP solvers improve their numerical stability.
The MILP solver adds a distributed branch-and-cut algorithm and the ability to report multiple solutions.
PROC OPTNETWORK and the network solver (accessible from PROC OPTMODEL) add a path enumeration algorithm to find paths between specified nodes. The network optimization action set adds the corresponding path action.
The connected components algorithm in the network solver adds support for the thin internal graph format.
The LSO (local search optimization) solver is added and is called by PROC OPTMODEL.
PROC CLP (constraint logic programming) is added and runs on CAS. You can choose to run PROC CLP on a single machine or to distribute its execution across multiple nodes.
The optimization action set adds two actions, loadMps and convertMps, that help convert an .mps file on the client to a CAS table that can be accepted as input by PROC OPTLP and PROC OPTMILP in SAS Optimization

For more information, see the SAS Optimization 8.2 documentation.

How similar is the new Viya optimization tool? Is there any functionality not included yet?
