Sorry for replying late, real life was happening and no web access for
last couple of weeks and more taking its toll.

I *think* the frustration was on two counts -

a. The amount of time it took to arrive at a solution

b. Then the amount of time it took to arrive at the next solution.

I do understand that at times it may be unable to provide any more
solutions, in those cases aptitude should say that . Also if there is
some kind of internal clock or percentage by which a user would know
when the solution or next solution would be coming, it would take out
the uncertainity to a large extent.

I have no idea if either of the above are workable although as a user
I would appreciate it as probably would people who value precision and
definiteness.

I hope you get what I'm trying to say.
