Your constraint problem has far more than two solutions, so saying you
want "both" of them is confusing.  I guess you're using the backtrack()
limitation to try to force it to return the solutions in different
sequences, and you want the first solution from each sequence, but it
would be better to write the constraints to really produce the set of
solutions you actually want.  Changing the search algorithm is a very
hard-to-control substitute for that.

What is it you're really trying to accomplish here?
