Re: [computer-go] Bad effect when tree node limit reached

OK, I have changed it so that it now prunes nodes with low simulation counts instead of preventing the creation of new nodes. It works better now. Thanks. Michael Williams wrote: Yes, it is a hard limit. If it has been exceeded, nodes cannot be expanded into more nodes. I am not removing

Yes, it is a hard limit. If it has been exceeded, nodes cannot be expanded into more nodes. I am not removing any nodes. Olivier Teytaud wrote: Hi; the "node limit" is a hard limit on the number of nodes ? if yes, when you reach this limit, what do you do - you remove some nodes with small n

My engine is basic UCT+MC. I've been letting it ponder on small empty boards with a certain komi to see if it begins to converge to the correct position value. It does as long as the tree is allowed to grow. But as soon as the tree reaches its node limit (with simulations continuing), the posit
