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.

Callbacks from CP for .Net languages like C#

Callbacks are available from CP using C++ or Java, but not if using the API from C# (or any .Net language). This seems to be very strange as the internal structures must be there inside the CP libraries etc in order to support the callbacks from C...

OPL function to assign a initial value or fix te value to a variable

The only way to do a warm start is by using OPL script.it should be possible in the variable declaration to give a start value. the same way if you want to fix a variable to a value you need to 2 lines of code to fix the upper and lower bounds... ...

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....

OPL Lazy Constraint Pool

At http://www-01.ibm.com/support/docview.wss?uid=swg21681643, it is indicated that it is not possible to add lazy constraints in OPL Script. I know OPL is not a programming language, but it is quite important to be able to add lazy constraints in ...

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...

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 ...
