You're most probably doing it already (I just wondered about the list
comprehension): Can you do numpy.sum(F(lasers)) in your function (that
is, is 'lasers' a simple array)? Note that numpy.sum (or a.sum()) is
much faster then the builtin sum() for large arrays. Also use
numpy.amin(<array>) instead of min() and stuff like that.
