Version 12.8 of CPLEX Optimization Studio is available on Passport Advantage for commercial users, through the Academic Initiative program for academics and students, and as a trial version for all. It’s not yet on DOcloud, but that will come soon.
Here are some of the most prominent changes:
– Performance improvements on a wide range of problem types
– OPL and the IDE available on MacOS.
– New callback framework in CPLEX, to avoid disabling dynamic search, and make sure that callbacks don’t interfere with the CPLEX search when not necessary.
