[Dip] Benders decomposition in DIP

Thu May 12 09:00:50 EDT 2011

Thanks Jiadong, Matthew, and Michael for your useful comments.  I will probably look to AMPL at first for a proof of concept - and perhaps consider Dippy at a later point.  Thank you Michael for pointing out this interface!

Dear Jonas,

There is a Python interface for DIP called Dippy (I am one of the developers/maintainers - Dippy is available as part of CoinBazaar) that allows you to easily customise the cuts generated during solving. You might be able to use that to implement Benders decomposition. It should be almost as straightforward as AMPL and you will be adding cuts within the solving framework which is not easy with AMPL.

Hope this helps, Mike
