there's a player on FICS called fjjvh. This program is so weak... It's almost as good as a random move generator. You might want to test this one (although I dont know where to find it).

Could this be Folkert van Heusden's engine Pos?

Here is the bottom end of a personal rating list of mine. BrutusRND and I believe Ram are random movers (HGM is the author of Ram).

Pos, CPP and N.E.G. are not buggy, but are engines without search. N.E.G., for instance, plays a move based on counting the number of attackers and defenders of each square, with a light preference for checks. But the gap between those engines and engines that search is enormous, and not bridged well enough by other engines to make sensible ratings for them.

Ram is not so much a random mover, as well a normally searching engine with random evaluation. The idea was that this would bias the search towards positions with large mobility (the 'Beal effect'), which should equip it with some intelligence compared to random movers (and the more when you let it search deeper). This does not work well, though, as it still recognizes checkmates. So the main effect that makes it stronger at larger depth is that it is able to recognize mates from a larger distance, when more or less aimlessly diffusing his pieces over the board. This makes it look very imbalanced: it plays like an idiot all the time, and then suddenly announces a perfect mate-in-6... To make it work would require some mechanism to prefer the mates by making that they on average result in larger random evaluation, by having choice from more random evals. But this would require you to somehow continue searching beyond the mate. E.g. allow only null move to a side that has lost his king, so that his opponent can hunt at leasure for the largest random eval, while he has no means at all to dodge good scores the opponent comes up with. The larger the tree where the opponent could do this, the better his score is likely to be, building in a preference for mates close to the root over those far from the root. Haven't tried that yet, though.

Hi,

I can contribute an old and fairly weak engine of mine written in FreePascal called mACE.

Hi Thomas,

I will include mACE. I knew of it already. I am not sure how or why I missed it.

I probably missed some others also.

Mobility is one of the most important things in a chessprograms evaluation function.

Does a program exist, that only has mobility (the difference between the number of white and blacks pseudomoves in the evaluated position) in its evaluation function? It should also know of mate, stalemate, 3xRepeat and evt. insuff. material, but nothing about the value of the pieces etc.

It should play fairly well; I once tried to exclude material from my program Dabbaba.

Best, Jens

NB. A new version 4.18 of dabbaba is available now - but that is not relevant for this tournament.

Saw that. How much stronger do you estimate it should be?

I have sent you an email.

It has this information about the strength:

The old version 2.62 scores 26/100 against Rybka4 (reduced to 2% strength).
Version 4.18 scores 40/100.
The games are played at level game/4minutes and both programs use the same opening book.
