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:
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,
Post an idea
Upvote ideas that matter most to you
Get feedback from the IBM team to refine your idea
Help IBM prioritize your ideas and requests
The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.
Receive notification on the decision
Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.
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...
Improve OPL Interfaces by providing field access infer by using the OPL model schema
Modify coefficient, adding variable, iterate on tupleset, modifiing dataElements and almost all operation in the OPL interface are really counter intuitive. Object uses by OPL are not directly compatible with the framework object. Ituple!= Tuple. ...
Manipulating Date in OPL is tedious. One needs to load them as string, then use script to convert them in date and access fields of this script object (month / year ...). Furthermore, it is not even possible to create a Date from a string in scrip...
Would be great to have not only a Matlab interface to CPLEX, but to OPL as well. It would facilitate. model deisgn (.mod) using OPL (way easier than working directly with CPLEX. model modification, re-run, post/pre-processing computations using a ...
Piecewise function with input as coordinate (x,y) of curve's points
the actual piecewise function in OPL takes as input abscissas and vector coefficient to construct the function.Many time people have user have the (x;y) coordinate. to do that you need to write OPL code to find the vector coefficient.Would be grea...
Function to Add tuple to a set in OPL not only in OPLscript
Have an OPL fucntion to add tuple to a set.It will avoid to use OPL script to populate them whish is slow and increase complexity of modeling.A work around that I use it to create identical Set of tuple in OPL and use OPLscript to just copy them i...
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.
Is there an equivalent of Cplex.SolveFixed() for OPL Script ?I'm looking for dual costs of a MILP.So I'd like to1) solve it to get the solution.2) solve the corresponding LP with fixed integer variables3) get dual costsI don't know in advance the ...
