[Coin-symphony] Three questions

[francois dionne]

Dear mailing list,

I have Symphony, downloaded using "CVS checkout" on 2005-08-17, and I have a 
few questions.

1. I think that in SYMPHONY/include/BB_constants.h, SYM_INFINITY may be too 
small. In one of my mixed integer problems, all of the variables are much 
smaller. However, some of the largest coefficients in the constraint matrix 
are bigger, around 192*2^26 but no more than that. They are in the columns 
of continuous variables. Is it safe and useful to increase the value of 
SYM_INFINITY ?

2. If I tell Symphony to keep a warm start, solve it and then tighten the 
integer variables's upper and lower bounds, can Symphony use the warm start 
information for a warm re-solve?

3. Finally, I appreciate it when Symphony tells me that a solution has been 
found or that there is none, but is there a way to tell it not to dump the 
whole solution vector on the screen? I think I use the default verbosity, 
which would be 0 .

That will be all. Thank you in advance and have a nice day.
