Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Improve populate output

Currently (including the CPLEX 12.9 beta), the output from the populate method lists the number of solutions currently in the pool and the number of solutions "replaced". Use of the term "replaced" signals to the user that changes were made to the pool, but in fact looking at and rejecting 100 solutions results in "100 replaced" in the output, even though the pool is unchanged. Saying "100 solutions evaluated" or perhaps "100 solutions identified" would be less confusing. It would also be nice if the output would indicate how many (if any) solutions in the pool are new as of this call to populate. For instance, in lieu of "Solution pool: 5 solutions saved (97 replaced)", the output might say something like "Solution pool: 5 solutions saved (2 new; 97 evaluated)".
