I have been making some modifications to the diving heuristics
which should help.<br>
<br>
I have a lot of changes to trunk - but I think the unsafe ideas
are not normally switched on - so should be safe to update trunk.
Will do it tomorrow.<br>

Hello,<br>
<br>
I split an huge problem in several little problems which sizes are
(IMO) equivalent.<br>
Solving each of them lasts several seconds (no more than 2-3
seconds) except one (several minutes).<br>
I tried different combination of options (w/wo diving, w/wo zero
root...) without any success. (threads 104 ratio 0.05 cutlength 40
multiple 4 divingv on divingl on divingf on divingg on divingc on
divingp on zero root)<br>
<br>
Have you an idea to help this problem to be fastly solved ? Or my
splitting and the cost function
are not well balanced ?<br>
