[Coin-symphony] Specialised branching via user callbacks

[Michael O'Sullivan]

Hi everyone,

I am trying to speed up SYMPHONY's performance by forcing variable 
branching on "important" variables first. I am building a candidate list 
in user_select_candidates, but I cannot find any examples of how to add 
branches (specifically variable branches) to the candidiate list. Is 
there a good example of user-defined branching anywhere out there?

Thanks in advance folr any help. Reagrds, Mike O'S
