Is it time to make chess tiger free engine

[Chris Taylor]

[quote="eriq"]unless chess tiger can make another 100 pt. leap, perhaps it is time to retire and live the good life like ed. He was one of the wisest of all, first he retires then improved an already great engine, allowed others, his code, and is now immortalized as an icon in computer chess history.

Chess tiger could do the same, but better by doing all of those things but adding a linux binary as well. Let's face facts any more improvements would take months of work this is time wasted away from family, child, which is more important ask yourself and even if you could do it ct would still lose to rybka or zap or hiarcs or shredder or fritz.

maybe it is time to just let go.[/quote]

Hi

This is a provacation on your part, Not only do I not agree, I hope Christophe goes on to make Tiger with super strong claws. This is not even mentioning the bite of a real good player? Hope he makes more money as a result of your post, as this will also help in paying the bills.

I have a challenge for you. Play against Tiger, and show Christophe some errors the proramme is making. Call this constuctive critisism, then you will be helping all the computer community! Instead of wishing for a lot of hard work to be given away?

Please consider loosing the negative critisism and replace it with some pro-active help. Bet Christophe can handle some positive help, and a little encouragement.

YMMV, just a few thoughts...

The only question is if it is legal to do it without releasing the source assuming that fabien agree to it but if it is legal that fabien makes money from changing fruit without releasing the source then I see no reason to think that it is illegal that other people make money assuming that there is no objection from fabien because he will also get money.

Hi Uri,
the situation of Fabien is of course different because he is the author and only owner of the Fruit code. Thus, he is the only one who can do anything he wishes with it.
One of the things he did, is to allow others to use that code provided some conditions are met. More specifically, he allowed others to "license" the code at the conditions specified in the GPL.
Since GPL requires that all modifications to source are made public, there is no way around this unless Fabien grants (to everyone or a single person) another kind of license, something he can always do since the original code remains his own. So in your scenario "no objection" would not be enough, explicit permission is needed.

I meant the same.

It is obvious that we assume that he has an objection if nothing else is claimed by fabien.

When I used the word no objection I meant to explicit permission
and I thought that in case that Fabien says that he has no objection it means giving explicit permission.

Maybe formally fabien needs to say more than having no objection but the idea is the same and I see no reason for fabien to say that he has no objection unless he plans to give explicit permission.

At blitz time controls Tiger performs as strong as any other engine on my computer. After 132 games, it is currently the 7th strongest engine. Provided that I dont have commercial fruit, Fritz, junior and Zap and that I tested a personality of Shredder which isnt much better than the default, I have gotta say that chess tiger is at least one of the strongest 15 engines.

According to CCRL 40/40,

Code: Select all

13 Chess Tiger 2007 2793 +17 −17 44.8% +35.2 40.2% 113 

CGET 40/20

Code: Select all

25 Chess Tiger 2007.1 2731 21 21 628 48.7 % 2739 41.1 % 

Original rank on the above list should be 15th because they have more than one version of Rybka, shredder, Zapchess, Toga and few other engines.

My list

Code: Select all

7 Chess Tiger 2007          : 2727  132 (+ 64,= 35,- 33), 61.7 %

Is there a reason to make one of the strongest 15 engines free provided that the previous versions were commercial? I dont think so.

Eriq, there is a lot of time for Christophe to retire. He is too young and have many ideas. Perhaps by now, with his new family, he cannot invest so much in Tiger, but sooner or later he will and then we could see if really he was left behind without remedy.
I, as a performer in a craft, writting, would feel bad if someone told me to go even if said with good intention. Probably you too.
Nobody is ready to accept that and less a guy still in the prime of his powers..

You may be correct but I think that we do not know exact details about number of sales per engine in order to be sure.

I don't think Chess Tiger should be free.
I think Chess Tiger is to cheap. CT2007 is 35 Euro, Shredder 10 costs 50 Euro. So I think Christophe is giving away his engine to cheap and should demand 15 Euro more.

[Karmazen & Oliver]

? XD ... good try ¡¡

maybe not Free ?¡ why need a version free ?

hiarcs not have a "good" version free, only is a "previus beta" program

rebel 2.0 decade, have "only" 2300 points.

fritz NEVER have any version FREE ¡¡¡ XD, it´s a pyme ¡¡ not a ONG ¡¡¡

and tigers only need have A GOOD price... ¡¡ I only buy tiger the fist time on palm because it´s have a good price 12 € ~, other programs, for palm have a lot of money... DOuBLE ( genius ) . TRIPLE ¡¡ ( hiarcs )

I like his style...

maybe... free open SOURCE ¡¡¡ ? XD. maybe a good joke ¡¡

bye. since spain... Oliver.

[Cubeman]

It he wants more sales,he should make the Palm version demo more user friendly and perhaps consider a native PPC version.I only buy engines now, that I can test to their full potential.Anything less I just say forget it.
