[Coin-symphony] How to get quickly a solution ?

[Renaud Lepere]

Hello,

 I plan to use Symphony for solving some simple MIP problems 
(such as knapsack), i tried also matching problems. I would 
like to find quickly a good feasible solution but i don't 
care about optimality. 

I get symphony from cvs and i succeded to build a problem
using sym_explicit_load_problem and solve it using sym_solved.
I would like to bound the computation time, so i tried to use 
"time_limit", but sometimes it is really longer than the limit 
(apparently the first call to fathom_branch is long) and if i 
add verbosity settings i see that the first feasible solution is 
long/hard to find.

Given a solution of the LP, i can round variables to get a feasible 
solution. How can i tell this to symphony ? Should i use a
call-back ?

I hope you can help me. 

Thanks,

Renaud
