saving data with a mouse-click instead of writing code through JDBC connector in CSV or other formats

I can currently browse it in the UI/IDE using the various inspectors. It would be nice if I could easily save this data to a file with a mouse click rather than having to write code, or add JDBC connections and rerun the model, etc. Typically what...

Human-readable status response

In the new multiobjective optimization support in CPLEX (Java API, but likely true in other APIs), querying status via IloCplex.getMultiObjInfo(IloCplex.MultiObjIntInfo.MultiObjStatus, ...) returns a numeric code (e.g. 107). This is difficult to i...

CPO interactive enhancement to write or query solution

CPO interactive misses some very useful command to simply query one solution value for a given variable with its name (allowing wildcards to display more variables) Today, the only way we can query a solution is through display solution command th...

Consistent handling for exportModel(), writeMIPStarts() , etc

The handling where methods like e.g. exportModel() and writeMIPStarts() is not consistent and not intuitive. In case no absolute path is specifies, exportModel() always writes the file parallel to the mod-file. Whereas writeMIPStarts(), while star...

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...

ODBCUpdate function needed

On the recent versions of cplex we have functions like ODBCRead and ODBCPublish for data management on Data bases engines, but it is also necessary to have a function like ODBCUpdate which corresponds to the old one DBUpdate function which allows ...

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 1...

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...

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...
