Why are no more updates planned? Are you stopping working on it or do you plan a commercial version?
Cheers

Sometimes in the life of a chess engine programmer, the ideas disappear, and you decide to terminate the project, but this is a "adiction" and you come back.
The other option is that he received good bussiness options $-)
Anyway, Rahman, good luck in your future projects, and my condolence to the Iran people affected by the earthquake.

I guess the first option.
In case of planning a commercial version he could write in his homepage:
"Please do not wait for a new *free* version"

I read in Readme.htm of ktulu the following:
STRENGTH 50, means that Ktulu uses 50% of its positional knowledge
It is not clear what does it mean.
My first thought was that I cannot divide knowledge to % and say that pawn structure is 20% of the positional knowledge when mobility is 30% and king safety is 25% but later I have an idea what it can mean.
Does it mean that the positional scores are 50% of the original positional scores when strength 0 means only material evaluation?

To Axel:
I'm busy with studying at university and uni classes have taken all my time.
However, if I release a new version, It will be a commercial one.
To Federico: Thank you Federico for your understanding.
To Pedro: I hope you can access to my site now. I don't know what happened.
To Uri:
There are several pre-defined tables for evaluating a position in the program.
When the program is initializing, the program will compute these table again
according to how STRENGTH parameter is defined. STRENGTH 0 doesn't mean
that the program has no any positional knowledge. In this case, it knows well
Pawn structure and a very little knowledge only, because it doesn't use predefined
tables for those part of evaluation. You should also have realized that in UCI mode,
this parameter is defined via GUI, and in this case, option.txt is ignored.

Rahman, I wish you all the best for your future (and for your country too)!
Will you still visit this forum from time to time? Anyway it was
a pleasure to 'meet' you.

Looks like your site exceeded the bandwidth limit already, good thing I've already downloaded it. If anyone needs the new version (Ktulu 4.2) send me an e-mail.

I know how hard university can be. I wish you well. I wish you also to have success with a probable future commercial Ktulu. I'm impressed of v.4.2, it really kickes engines-butts. You can't get rich with it, but at least make some bucks :-)

Also my condolences to you and your countrymen in this difficult time.
Axel
