[Symphony] Column generation with symphony

[Ted Ralphs]

Hi Ankur,

Column generation is no longer supported in SYMPHONY. Two options
within COIN are DIP (https://projects.coin-or.org/Dip) and BCP
(https://projects.coin-or.org/Bcp). I would recommend taking a look at
DIP first. Feel free to post questions to the mailing lists for those
projects.

Cheers,

Ted
