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 updateson them if they matter to you. If you can't find what you are looking for,

We developed a product based on .NET 6 that relies on CPLEX core functionalities and we need to make it run both on Windows an Linux operating systems. The .NET 6 libraries are platform independent but the CPLEX Optimization Studio only provides a...
a new parameter to control to force MIPStart if the variables are feasible
CPLEX choose to use MIPStart or not accoring to the heuristic. But sometimes the user think MIPStart values as particular variables is the best way to solve the problem. So we’d like to request a new parameter to control to force MIPStart if the v...
Superior approximation algorithm for finding Maximum (or large) Cliques in very large graphs. (Multi-Partite Graphs can be found)
Our maximum clique finding algorithm (that is polynomial in its run time) and which seems (from DIMACS benchmark tests) to run better than other methods that are presently available would be beneficial to IBM because it would allow you to solve co...
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 ...
We need a build for Linux ARM64. Preferably redhat enterprise 8. We're aiming our software for the ARM architecture and CPLEX for ARM is currently only available on OSX, but not for Linux. This is blocking us.
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...
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 ...
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...
