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,
Post an idea
Upvote ideas that matter most to you
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.
Would be great to have not only a Matlab interface to CPLEX, but to OPL as well. It would facilitate. model deisgn (.mod) using OPL (way easier than working directly with CPLEX. model modification, re-run, post/pre-processing computations using a ...
Extract from SAS PROC OPTMODEL COFOR new feature:Be able to run optimization solver invocations in parallel, in iterations of a concurrent FOR loop that is specified using the COFOR statement. The COFOR statement operates in the same manner as the...
Offers a way to interact with external code written in .NET from OPL.This feature would allow us to:• write a complex dedicated OR algorithm (such as a shortest path or flow algorithm) to be used as one step of a decomposed application• connect yo...
Actually we have to use OPL script to attach a relaxation priority to a constraint. It will be easier to attach this priority at the creation of the constraint. Reason is that a constraint tupleset can easily include a priority field:tuple rvConst...
Piecewise function with input as coordinate (x,y) of curve's points
the actual piecewise function in OPL takes as input abscissas and vector coefficient to construct the function.Many time people have user have the (x;y) coordinate. to do that you need to write OPL code to find the vector coefficient.Would be grea...
Produce log during OPL Extract phase similar to Solve Engine Log
Many OPL real-world optimisations spend a large proportion of the overall solve time performing extraction/generation and there is no log of what is happening during this time. There should be a log produced during Extract similar to the Engine Lo...
We are looking at CPLEX on zOS.Today, only compiling a C++ program can be used to drive CPLEX on the z platform. It would be much easier to be able to inject OPL directly in (concert, part of ) CPLEX for z/OS.
