> With less than 50 tiles, you are getting close to the territory where the move plus the five plies could conceivably use up (1+5) x 7 = 42 tiles - so you want to switch to Many plies. The more tiles in the bag, the more sims are needed - but I reckon 3000 sims is sufficient for most cases. >
I just tried a 5-ply sim and the difference in valuation of 2 competing moves at iterations 14,000 and 15,000 changed by 0.4. I did not expect that much so far in, but it makes sense. 5-ply is pretty deep, and it's an exponential gain in noise for each ply, so it's not that surprising. for moves with evaluations of 1.0 or less between them it would seem that even 3000 its is WAY too little for 5-ply.
