Re: Board adaptive / tuning evaluation function - no NN/AI

That brings me totally off topic, I have some other ideas: Has anyone used a NN for hashing or board state representation/encoding ? One could train a net with few inner nodes/neurons (e.g. <25) to turn a representation with many (e.g. 385) neurons into that inner representation and back to the inp...

Re: Perceptron for reduction / extension / other things

Using a neural net for anything devolves into some manner of alpha/leela methodology. In this case we are talking about having a policy network as found in the original alpha papers (for the first go engine, I believe) The policy network would generate a weight for how important a particular move (o...

Re: An AMD compiling hunch

Are we also going to call instructions like XLAT "phony baloney" also because it perform poorly (even on Intel?) The idea that GCC doesnt have a say is wrong. The goal of the compiler should be to produce the fastest binary given the information it has. If the information spawns from the "native" sw...

Re: Space/Time Tradeoff in year 2020+: What can the community do with 20TB+ Hard Drives?

Why inject leaf removal into this? A sparse-in-memory table can trivially be converted to a simple compact dense list (just skip the zeros) and can be done in place (no extra memory required.) Then at least part of the stored N-bit hash codes in that dense list are mostly sorted in long ascending ru...

Re: Komodo 13.2

Thinking about this....

It shouldnt be hard to write a UCI stubber that emits uci parameters, from a file given on the command line, right after it hands off the "uci" or right before it hands off the "isready" command.

I dont know if the 36 bytes per node you are talking about is worth it, but from your comments "assuming 20ply depth" "for 10-seconds" Storing these graphs in enormous memory is trivial (minimizing time), storing them far more compactly than what is time-efficient also trivial (minimizing space.) Th...

Some things to keep in mind. o) Some engines are much better than others at re-starting a search with an already-filled HT, for whatever reason(s). o) transposition tables can now be so big (32GB, 64GB...) that holding even multi-minute searches as a non-lossy connected graph might now be a superior...

Intel is decimated, while having supply shortages, while rushing for a secure redesign.
