Re: Adding a random small number to the evaluation function

The CT800 has this as configurable option: off, +/- 10, 30, 50 centipawns. It is random noise added directly to the eval of a position. Disabled for the endgame eval.

The point, however, isn't raising the playing level, but giving more game variety.

Re: new chess computer: CT800

oh, I even have a real hardware MM4 somewhere in the basement, from the late 80s. Ed has explained quite a lot on how Rebel works, and you can download the executables on his website - but not the source code. It isn't FLOSS. Next thing is.. well, just take a look at this example (line 281 ff): http...

Re: new chess computer: CT800

You must contact Martin, I believe. I have not found nothing for that in Internet, but maybe i did it wrong. I used the wayback archive to get the archived version of the Colossus website. The main issue I see here: the program has been around since the C64 era, but always as closed source. People ...

Re: new chess computer: CT800

ok, I was able to find out some things via the wayback archive. The download back then was a Windows executable. The CCRL has Colossus 2008b in green colour, which means "free" as in "free beer", but no source code. I guess that is why I didn't even look at it since I only checked out the orange ite...

Re: new chess computer: CT800

Colossus? I do remember that from the C64, that is really oldschool. :) Interestingly, Wikipedia states it was converted to C, and the 2008 version had a whooping 2642 in CCRL. That is miles ahead of what the baseline version of NG-Play had to offer, which is rated at 2173 at CCRL. Unfortunately, th...

Re: new chess computer: CT800

I have insisted in new programs, but of the old guard. It would be LOT more interesting if you can get one of those old programmers to put at your hands one of his products in exchange of a manageable condition. The Phoenix Chess System allows for a lot of emulations. Obviously, that is the old pro...

Re: new chess computer: CT800

I will try to convince some manufacturer. That's why I included so much documentation especially on the hardware, as to make it easier to get such a thing into production. Maybe Millennium will show interest if enough customers tell them that they will not buy the next Lang software in a different h...

new chess computer: CT800

So here is a new dedicated chess computer, the CT800: http://www.ct800.net The raw playing strength of about ELO 2100 may seem unimpressive to quite some of you who are into engines in the 2800+ range. However, the power consumption of the total system under computing load is just 0.4W. That would b...

Re: Neuronet plus conventional approach combined?

Thanks, that's an answer from the chess-neuro-expert No. 1. I mean, computers are better than humans with their current tactics approach, but strategically, human masters are still better. Only that humans fail tactically before their strategies might come to fruitition. What is your take, are neuro...

Neuronet plus conventional approach combined?

A question that I've been thinking about for a while: Neuronets alone suffer from tactical problems because these networks are designed to answer minimum changes in the input with minimum changes in the output. Chess is a game where displacing one piece by one square can make a decisive difference, ...
