in VUG  "What's New in CPLEX Optimization Studio 12.6", December 11, 2013 by Mary Fenelon following is mentioned (Chart 11)

Additional OPL scripting methods and API
Scripting
- Lazy constraints and user cuts
- Solution pools
- Priorities
- Problem queries

I do not find any example for These new Features - not even in release notes. Is here some more documentation or could you provide examples for the new Features.

Kind Regards

Hi

as said in http://www-01.ibm.com/support/docview.wss?uid=swg1RS01648 you should use at least 12.6.0.1

Do you ?

Hi,

can you try with 12.6.0.1 ?

Indeed with 12.6.1 this does not work.

Do not hesitate to log a PMR : http://www-01.ibm.com/support/docview.wss?uid=swg21507639
