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).

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...
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...
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.
CPLEX object create by oplrun and concert shall be equal
the CPLEX object created by an OPL model is not the same as tyhe CPLEX object created with concert technology.It creates limitation and complexity that prevent people to use OPL in many cases, such advance algorithms with call backs manual cuts......
Extend CPLEX for Matlab to support the Matlab Compiler
CPLEX for MATLAB is an extension to IBM® ILOG® CPLEX Optimizers that allows a user to define optimization problems and solve them within MATLAB's development environment. However, an optimisation module developped with CPLEX for MATLAB and compile...
Is there an equivalent of Cplex.SolveFixed() for OPL Script ? I'm looking for dual costs of a MILP. So I'd like to 1) solve it to get the solution. 2) solve the corresponding LP with fixed integer variables 3) get dual costs I don't know in advanc...
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...
