Comment (by mgalati):
These are probably for cases that solve in the root node and the overall
optimal is probably being found before Alps is updated. Either way, Alps
should init the best relaxed at -inf, not inf. Ted - can you correct that.
I am not sure about the depth problem. My guess is that it is another
initialization issue. It seems to be init'd at INT_MAX instead of 0.
