Marco,

I'm not aware of any guide to help tune these parameters.  Proprietary 
software companies spend a lot of effort tuning their default parameter 
settings.  I don't think anyone plans to spend that amount of time with 
COIN-OR, so we need to come up with some other approaches.  That's 
actually something I'm looking at right now.

For now, if you have representative instances you wish to solve, then 
you basically just do some tests on those instances with various 
parameters and see what works well.
