Hi Nick,
When writing a software for an engine there are 3 main tasks that give its strength and style of play:
1) Search
2) Evaluation
3) hash table
of course there are others. I do agree that gideon pro is not 100% the same but could be maybe 90% that is why i also say close but this has to be test to see how close it could be. Sadly i can not do that because i only have the gideon pro UCI. Nevertheless I had include in my to do list test the strenght of this gideon pro UCI.
Best Regards
Ricardo
Right, but I still don't understand what you are asking to be confirmed? Your posts keep looking for confirmation that Gideon 3.1, Gideon Pro and Gideon Pro UCI are the same after you change the Hash on Gideon Pro UCI version back to the original Gideon Pro Hash. All you will have then is still a modified UCI version of the Original Gideon Pro but not Gideon 3.1.
Ed could have confirmed Gideon Pro and Gideon 3.1 are identical, but he did not, he just pointed out that he made a big mistake in the Hash when he converted Gideon Pro to Gideon Pro UCI. There is no mention of Gideon 3.1. He also indicated that other minor changes were made to Gideon Pro UCI in the conversion. Therefore even with a Hash correction Gideon Pro UCI would not be the same as Gideon Pro DOS.
Under evaluation for example if two positions are calculated the same, one is a Fork and one is not. How would a program choose? Would it always choose a Fork because the programer prioritized this as the way to go or no?. Or is it Random choice. Or even always the first evaluation? There is a million subtle small changes in Evaluation alone that make the programs personality or ability different to a previous same version. Don't you think that programmers whenever they made a conversion, picked their last version of their software. Therefore it's impossible to pick Gideon 3.1 version 1 for example 3 months later when in front of the programer lies improvement version number 105, which in this case he would name it Gideon Pro instead of Gideon 3.1 for DOS.
In R30 you have 5 Play styles for Gideon 3.1 to choose. The Chessmachine has 3 play styles. Which of the 5 play styles compares to the 3 styles available to the Chesmachine? Howabout Gideon Pro how many play styles do you have. The standard Gideon Pro play style compares to which Gideon 3.1 if the assumption is that they are the same?
Kittinger's versions A, B and C are probably 99% the same but its some small changes that give people the feeling that they are different.
Chessmachine Gideon 3.1 has been thoroughly played and there are plenty of game examples that could be used for testing. I am not sure if Micha has any BT Tests for Chessmachine Gideon 3.1 but they might be useful for you to do some more comparisons.
As for R30 Gideon 3.1, you can be sure that this program will be played, tested and reported on extensively.
All the best,
Nick
