IBM Data and AI Ideas Portal for Customers

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.

In OPL ODBC connection, add a setting for batch size

The prebuilt ODBCConnection allows OPL to access databases using ODBC.One way to optimize database access is to tune the execution batch size.With older versions of OPL that included DBLink, this was the dbUpdateBatchSize parameter.

Bring MATLAB interface back for CPLEX

Please bring back the MATLAB interface for CPLEX. We rely heavily on this feature since toolboxes we use are Matlab exclusive.

Callbacks from CP for .Net languages like C#

Callbacks are available from CP using C++ or Java, but not if using the API from C# (or any .Net language). This seems to be very strange as the internal structures must be there inside the CP libraries etc in order to support the callbacks from C...

Add support for Java 11 in CPLEX java API

Currently, CPLEX and CPO provide a java API to the engines.This API currently supports Java 8 (IBM SDK and Oracle Java).A more recent versions of Java with LTS is Java 11 - It would be nice if CPLEX Optimization studio officially supports Java 11 ...

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...

new DBlink for cplex OPL optimization studio

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...

Enhance .NET API for maps

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 "...

add doopl in the CPLEX distribution

relying on docplex python API got much easier since docplex was included in the CPLEX product. doopl which is a python package that allows to call OPL model from python code can be download from but having doopl in ...

Implement nonconvex quadratic constraints in CPLEX

CPLEX already supports nonconvex quadratic objectives, but not yet constraints, even though they bring a lot of flexibility in modelling.

OPL language enhancements : cannot slice with nested constraints on subTuples

I've been a happy user of OPL language, which has lots of wonderful features. However, there is one remaining recurrent issue in data modeling, which prevents some intuitive modeling. This is called "cannot slice with nested constraints on subTupl...
