I don't think that it is a matter of being dealt them, sorry to be unclear. I think you may have to make them and then break them. So now it is not clear to me if your algorithm handles that. >I do not have a special algorithm to solve Pile On, but only search >the game tree using backtracking.

Yes indeed, and while I am quite busy this week, I will try to do so. Right now I am trying to hack PySOL-FC so that you can input a starting configuration of cards, and also save each state change so that you can replay a game that you have won. But today is not a day for hacking for me, so this will take me a while to do. >Very thrilling!
