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.
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...
Make CP cumulFunction and expressions accept float instead of int
cumulFunction and expressions currently only allow the resource usage to be int which is not useful for all resource types. Whilst a workaround of multiplying the int by a large number to approximate the float is possible there are limitations and...
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.
Improve OPL Interfaces by providing dynamically typed API and a “façade” compatible with the .NET framework
Using OPL interface in .Net is cumbersome. Manipulate data elements object and result is far from being trivial.By example, instantiate an int look like that:OplDataSource dataSource = new MyCustomDataSource(oplF);internal class MyCustomDataSource...
Improve OPL Interfaces by providing field access infer by using the OPL model schema
Modify coefficient, adding variable, iterate on tupleset, modifiing dataElements and almost all operation in the OPL interface are really counter intuitive. Object uses by OPL are not directly compatible with the framework object. Ituple!= Tuple. ...
Dear developers. I thought that this idea either was already posted or perhaps is considered inside other idea related with ODX, but anyway I do want to ensure that next enhancement to cplex optimization studio get done: until opl 12.6.3. the fetc...
When attempting to use the reflection mechanism of OPL CPLEX API under .NET (version 12.9 but same problem seen in documentation of latest version), I stumble upon an error on my first implementation of a missing method "NbDim" for the map class "...
