From 241156da6f35cb888253e6b8814e7b61a76b4fc7 Mon Sep 17 00:00:00 2001 From: tslil Date: Sun, 30 Aug 2026 19:46:07 +0100 Subject: TD(lambda), and a big rework NOTE: 6x6 weights are as-yet untrained On the performance side: * switch from linked-list chaining hash table to direct mapping * cache check_win by hash * persist transposition tables across plies (this was a big deal and difficult to puzzle out) * add align directives to the network floats * prepare_nn_input gained a small LUT to avoid branching (i suppose you might call this 1D embedding) * apply mtune=native for the native builds On the correctness side: * Zobrist has now includes the ply parity * the network now predicts something in [-1, 1] using tanh (approximated by polynomials) * the training object is now MSE because we're learning a value estimate * use .clangd instead of compile_commands.json On the training side: * completely forgo human-derived data set * implement td(lambda), self-play, tournaments --- include/xorshift64.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'include/xorshift64.c') diff --git a/include/xorshift64.c b/include/xorshift64.c index 0a68c71..c758a47 100644 --- a/include/xorshift64.c +++ b/include/xorshift64.c @@ -1,5 +1,5 @@ /* - This file is part of ct. + This file is part of ctak.
