John,

Obviously, i mean truly deterministic.
If parameters are not the same, i don't expect to have the same solution.

As mentionned in my first message, the following Lp problem /https://www.dropbox.com/s/0i7c84lbm2pvyl3/t1.lp?dl=0/<https://www.dropbox.com/s/0i7c84lbm2pvyl3/t1.lp?dl=0/.>
may generate different solutions (/https://www.dropbox.com/s/zcu8kwv9ukipaqe/t1_0.sol?dl=0/ or /https://www.dropbox.com/s/jc1co4yeg9i13vw/t1_1.sol?dl=0/ )
with the same following command-line
/bin/cbc t1.lp threads 104 ratio 0.05 cutlength 30 divingV on divesolves 301 multiple 1 branch printingOptions rows solution t1_0.sol
on the same machine.

Regards

Yves
