  In addition to that, I'd say that it's not a good idea stop the analisys in
all the places of the tree. I mean, you can consider necessary to finish
analisying a branch of the tree to give an accurate evaluation. For example, I
only test the time condition in some places of my program, where I think it can
stop the search without missing information.
