IBM Data and AI Ideas Portal for Customers


This portal is to open public enhancement requests against products and services offered by the IBM Data & AI organization. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


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:


Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,


Post your ideas

Decision Optimization CPLEX & For Watson Studio

Showing 103

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.

Add Python 3.12 and 3.13 binary wheel distributions for CPLEX

The Python Package Index only contains distributions of CPLEX for 3.11 (see https://pypi.org/project/cplex/#files). Please upload wheels for Python 3.12 and 3.13.

Add Apple Silicon builds of Python binary wheels for CPLEX

The Python package for cplex on the Python Package Index (https://pypi.org/project/cplex/#files) only provides macOS binaries for x86_64, not for Apple Silicon. Please upload binary wheels for Apple Silicon. In my industry (astronomy, astrophysics...

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 https://pypi.org/project/doopl/ but having doopl in ...

read solution from cpo file

For CP-Optimizer, it would be great to have the ability to read a given solution from a file and pass it to a cpo model as a starting point and also enable to check this solution feasibility

Ability to control cplex memory consumption

Nowadays optimization runs are more and more conducted in the cloud, in kubernetes environments. In kubernetes, the processes run inside containers in what are called pods. To prevent a pod to be killed when the node (machine) capacity is exceeded...

Interface between CPLEX and .Net CORE 5 on LINUX

We are developing applications using .Net CORE 5. This is a great language to develop solution on either Windows or Linux. We have no issues using CPLEX with Windows as we have the cp_wrap_cpp_dotnet2010.dll running but we miss a Linux version of ...

Nonlinear solver for CPLEX

Add nonlinear optimization capability to CPLEX. Many real-life models are nonlinear by nature. CPLEX solver requires a linear model to work. A good nonlinear solver can often times overperform a linearized form of a real-life model. Having a nonli...

Run optimization solver invocations in parallel

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...

Calling external .NET code from OPL

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...
