I wouldn't expect it to get much better, unless the tabu size was
too high and stifling the move selection.<br>
But it could be better, try it out. If you do, please let us the
know results here (good or bad).<br>

This should be fixed for 5.5.0.Beta1 (hopefully released
next week).<br>
IIRC, It only happened on small datasets, usually when
they are close to optimality. Nevertheless, it's a bug
(now fixed).<br>

I know I give little details b ut I don't know

If someone can point me into some direction I can
search and provide more info.<br>
