Dear COS users,

We are putting the last touches to the next version of CPLEX Optimization Studio.  Version 12.8 should be available to all in the first half of December.

Here are some of the most prominent changes:

• Performance improvements on a wide range of problem types, notably for CP Optimizer
• OPL and the IDE available on MacOS.

You will find more details at https://ibm.co/2ywagsU.

I will be looking forward to having the version 12.8 for the following two aspects :

• Average time CP Optimizer needs to find and prove optimality on integer problems has been halved!
• The APIs IloCP::getObjBound() and IloCP::getObjGap() give access to the bound and the gap.

Dear IBM,
I am currently using 12.8 and trying to access the bound and gap since it would be a great help on my research.

However, I cannot identify the function names: getObjBound() and getObjGap().
Please check out the screen captures.

Thanks,
Andy

Hi,

unfortunately this is not yet available in OPL and you could log a Request for Enhancement

https://www.ibm.com/developerworks/rfe/execute?use_case=changeRequestLanding&BRAND_ID=401&PROD_ID=1290&x=18&y=15

In the meantime you could use in OPL an external java call to get that information

regards
