In the C++ API, there is the method IloExtractable::setObject()In the Java API, there is no equivalent on IloAddable. This is needed because it is useful to create a new IloIntVar from cplex.intVar(), and then associate a Java object to that varia...
OPL Script function to see which variables exist in model
Using OPL script, is it possible to know whether a given variable name exists in model ? For instance, something like model.contains("x") that would return true if x is a variable in model. If yes, is there any way of knowing the type and the indi...
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.
cpoptimizer interactive should display any var and expressions
CP Optimizer interactive should mimic CPLEX optimizer interactive for these two points 1. In Cp Optimizer command line, enable to display the value of an IloNumVar (floating point variables) and IloNumExpr2. enable write solution in a file
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...
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...
