Overall, it's a good read. Nitpicks: • The scalability graphs need to be clearer. Maybe add a caption or change the single-threaded label? I looked at the graphs first and took a bit to figure out why "single-threaded" outperformed all else. • The RAVE section wasn't all too clear. I think

Dear Isaac, I'm about to work on heavy playouts, and I'm not sure how to choose a move during the playout. I intend to have weights for various features. I thought about 3 versions: 1. In a position, calculate all the weights and the total weight. Then, play one move i with the probab

You have the most control with option 1. You can implement this fast by keeping the sum of the weights for each row and for the total board. You then "roll" a number between 0 and total_weight, and advance through the rows subtracting the probability of each row until you would cross 0, then go alo

Hi Martin, thanks for the information and the report. In the abstract you write "...Fuego includes a Go engine with a playing strength that is competitive with the top programs in 9x9 Go, ..." I want to support this claim. Over the weekend I had the fun to watch some free 9x9 games of Fuego on
