I understood that the software has been improved considerably with regards to performance, scalability, front end, etc. Has there been any benchmarking studies performed lately with the existing LP/MIP/NLP solvers like CPLEX/ MINOS, etc? If yes, can I request a copy of the same. If not, could you provide a comparison.<BR /> <BR /> Thanks.<BR /> Very Respectfully,<BR /> Jay Mon, 17 Sep 2007 17:49:17 GMT https://communities.sas.com/t5/Mathematical-Optimization/benchmarking-SAS-OR-9-1-3-with-other-LP-MIP-solvers/m-p/4738#M83 deleted_user 2007-09-17T17:49:17Z https://communities.sas.com/t5/Mathematical-Optimization/benchmarking-SAS-OR-9-1-3-with-other-LP-MIP-solvers/m-p/4739#M84 We cannot directly compare against other solvers since we do not have a license. From public domain benchmarks, after adjusting approximately for different hardware, we seem to be very competitive with the best of breed. In some cases, we are worse; in other cases we are better.
