If conditions in pre-processing in .mod files

To maintain two (or more) similar models in one instead of in two (or more) separate .mod files, we need the possibility of using if conditions in pre-processing in .mod files without using execution blocks.

Get CPLEX-version directly from ILOG-script

We have code that has to run under 12.7.1 and older version. Unfortunately the API for warm-start has changed. We have either vectors.setStart(cplex); // 12.7.1 or vectors.setVectors(cplex); // 12.6 OPL misses a nice way to access the version numb...

Improve populate output

Currently (including the CPLEX 12.9 beta), the output from the populate method lists the number of solutions currently in the pool and the number of solutions "replaced". Use of the term "replaced" signals to the user that changes were made to the...

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...

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...

sin function in OPL

tuple breakpoint // y=f(x) { float x; float y; } sorted { breakpoint } breakpoints={<i,exp(2*sin(i))> | i in 70..135}; I am trying to code this while because of no sin function in OPL, I am not able to code this on OPL.

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...
