IvanHoe 999946a is the new open source champion ! I had a look at the game, no time losses, no illegal move bugs, IvanHoe really won fair and square against StockFish and destroyed the others

[Graham Banks]

Lucas - I'm reliably informed that the KLO versions of Ivanhoe only come with the original Ippolit source code, not the modified source code compiled to create the new exe.
If that is correct, does it still meet your open source criteria?

Amazing considering you do not have the strongest 46a version, as we discussed, due to no Linux available. That just goes to show you how strong the engine is- in any form.

Good work here, Lucas. Any way I can assist you in the future with Ivanhoe versions, I will be more than happy to help.

Best regards, and again very good work,

I've got a fine compile and the source code of IvanHoe 999946a here. So why would I need KLO's compile ? I seriously doubt his compile is better than what I have here...
Besides *.exe files are Windows executables

46a is the one I have no ? I mean v 999946a. Is that not the latest ?

Okay. Thanks for answering.

[Graham Banks]

Pretty sure that 999946h is the latest. I'm sure that George will correct me if I'm wrong.

I'm afraid Ippolit source + compiled version of a much improved but closed source version doesn't work for me. For the same reason I won't even test Fruit 05/11/03 (latest version of Fabien) unless Fabien decides to release the source code. I'm perfectly happy to test derivatives, clones or whatever people call them so long as they are open source. Most people aren't engine programmers so they don't understand this. All they care about is elo, which is a shame...
But taking an open source program and making improvements in a closed source form is somewhat unethical: you take from the open source community and give nothing in return. Progress in the field of computer chess has only been achieved by open source software being published and articles being written about chess algorithms. No closed source program has ever contributed anything towards the community. So I don't see why I should make any publicity for them or use their software. All other rating lists test these so I don't need to duplicate their work anyway.
When you release a good open source software (like Fruit 2.1) it allows others to study your source code, and make improvements, or find recipies they can apply in their code. Ignorants call this cloning, I call it progress, as it's the only method by which the field has made so much progress over the years. If there hadn't been great programs like Crafty, Fruit StockFish, no one would even have anything above 2500 elo today...
Anyway, I would be happy if more people could understand this, and stop these idiotic debates about cloning...

Yes and no. 46 is the latest- but following 46a you have 46e (along with 46a probably KLO's strongest 46 versions)- then you have 46f and 46h.
He is going to put "9." before each one of course. 46h is the latest- but my guess is the one you are using and 46e arestrongest- but not latest.

Remember- latest version is smallest number and largest letter!

i thought it was smallest number and smallest letter. my bad !
but you have to admit that it's not very obvious...
