I have done a lot of work in Access using VBA. Actually, I use GMPL, but Access controls the reading of the model, the solving, and (since I'm working on an integer program), it records in the database the initial LP solution and all the subsequent integer solutions.
Further, there is a form that displays the output (and captures it in a table) from GLPK, as well as controlling the parameters. And I've implemented call-back functions for the MIP solver; for example I can "duplicate" the Driebeck-Tomlin heuristic. So far, I haven't stubbled on any breakthrough on the specializing the callbacks. It will take me a couple of days to remove any confidential information and make it generic. Then I can release it. -Marc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andrew Makhorin Sent: Friday, July 04, 2008 11:48 AM To: Eduardo Mesa Cc: [email protected] Subject: Re: [Help-glpk] glpk vb > Hai, sorry by my english, I speak spanish.

However, at the moment it seems to be unavailable. If you need to solve an LP or MIP, why not to use the modeling language GNU MathProg, which is a subset of AMPL? _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
