Re: [Computer-go] Possible idea - decay old simulations?

The tree built by MCTS is very unbalanced - some branches are explored more thoroughly than others. Tweaking the algorithm to favor the newer results might result in an overall improvement, but it also would be subject to all the pitfalls of partially or unevenly evaluated trees. This is

[Computer-go] Possible idea - decay old simulations?

I've been using Leela 0.10.0 for analysis quite often, and I've noticed something that might lead to an improvement for the search, and maybe also for other MCTS programs. Sometimes, after putting hundreds of thousands of simulations into a few possible moves, Leela will appear to favor one,
