Re: Banksia GUI released

I see. Look like your computer is put to its limit of memory. It will be worse when playing since BSG stores all game info such as moves, scores, times... in memory as well as storing to its JSON files (banksiaplaying.json). The memory usage will be expanded a bit after each move and BSG writes dow...

Interesting issue! Frankly speaking, I am so rare to create such that huge tournament. Can you give me a few more info: - what is your OS, CPU and RAM? How many threads does it have? Win7 SP1, Intel Core i5 760 (Nehalem) 2.95 GHz, 4 core / 4 threads, 4 GB RAM. I usually run tournaments in two or th...

The first NN layer is overparametrized, that is where most of the weights are, but is computed efficient via incremental updates during make/unmake move. Yu Nasu came up with NNUE for Shogi in 2018: https://www...

Re: Banksia GUI released

phhnguyen , there are a couple of problems: 1. If you set a tournament with more than 10,000 games, then BSG starts to slow down significantly. The task manager shows that loading new games requires a full load of the entire processor core. The problem becomes even more serious on short time contro...

"Computerschach und Spiele" #5, 2002, page 10: Die Hardware, auf der Deep Fritz läuft, ist ein 8 x 900 MHz schneller Compaq mit vier GB Speicher.
