ADD A NEW IDEA

Decision Optimization CPLEX & For Watson Studio

Showing 100

Implement piecewise linear features in Matlab API.

As for all the other APIs, it would be great to add to be able to describe PWLs with the new features introduced from 12.7.0, also in Matlab. The procedure to write several PWLs can become quite cumbersome for a large amount of constraints.

Ability to solve Python/docplex model in CPLEX Enterprise Server

This request is actually for CPLEX Enterprise Server, not CPLEX Optimization Studio, but CES was not an option in the list of products. Currently CES is only able to solve models implemented in OPL. We would like to be able to submit and solve app...

Excel or/and .ods connector in OPL IDE on all platform

On Linux or Mac the only way to import data in the IDE is to write a custom OPLscript to inport a CSV file.

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...

use of GPU port for cplex

My question is if GPU processing could be introduced in MIP optimisation?

Dantzig-Wolf-decomposition with CPLEX

Extend the CPLEX-API to let reformulate a problem by CPLEX, notably a problem - which could be solved efficiently by a DW-decomposition. It should be reformulated by CPLEX to a problem (its dual) which could be solved by CPLEX's benders algorithm....

CPLEX: Make adding mulitple objectives consistent with adding one objective

In the Java API for CPLEX (presumably similar in other APIs), it is possible to create an objective and add it to a model in one function call, using overloads of IloCplexModeler.addMinimize() and .addMaximize() that take an IloNumExpr argument. D...

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 doopl in the CPLEX distribution on Watson Studio

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 ...
