IBM Data and AI Ideas Portal for Customers

This portal is to open public enhancement requests against products and services offered by the IBM Data & AI organization. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (

Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

Improve OPL Interfaces by providing dynamically typed API and a “façade” compatible with the .NET framework

Using OPL interface in .Net is cumbersome. Manipulate data elements object and result is far from being trivial.
By example, instantiate an int look like that:

OplDataSource dataSource = new MyCustomDataSource(oplF);

internal class MyCustomDataSource : CustomOplDataSource
internal MyCustomDataSource(OplFactory oplF)
: base(oplF)
public override void CustomRead()
OplDataHandler handler = DataHandler;

// initialize the int 'simpleInt'

I think that this can be possible to provide a method to do this more naturally:

dataSource.anInt = 3;

Instantiate a tupleset is harder:

// initialize the tuple set 'simpleTupleSet'
// first tuple
// second element

Providing a method like the following is probably easy to do (below is F# code but C# or java is almost the same):

dataSource.aTupleSet =[(1, 2.5, "a");(3, 4.1, "b")];

Modifying a coefficient in a problem base on a value on an other problem is also cumbersome:

double coef = subCplex.GetValue(subOpl.GetElement("Use").AsIntVarMap().Get(i));
IForAllRange forAll = (IForAllRange)masterOpl.GetElement("ctFill").AsConstraintMap().Get(i);
masterCplex.SetLinearCoef(forAll, newVar, coef);

Why not :

This kind of construct is possible with LINQ, SQL database client and F# type provider ( I suppose that this can be possible to wrap the actual OPL, Concert and CPLEX Interfaces to offer similar coding improvement.
