title: Ippolit
[ Hippolyta the Amazonian queen [1] Ippolit,
an UCI compliant open source engine by pseudonymous authors. A former CPW page of Ippolit by one of its authors from May 2009, was preliminary deleted due to a claim by Rybka author Vasik Rajlich, CPW would support piracy sites and who implied Ippolit is a clone or derivative from Rybka 3 [2] , apparently due to disassembling and decompiling.
Origin
In June 2010, Vasik Rajlich made following statement on Rybka and Ippolit, which was published by Sven Schüle in CCC [12]:
Ippolit is disassembled Rybka 3 with changes. The changes are considerable but not even close to enough to leave any doubt. Robbolito is an evolved Ippolit, with more changes and more cleanup. I haven't checked the other new engines yet.
The same day Zach Wegner published a technical summary by former anonymous author "BB+" alias Mark Watkins about Rybka and Ippolit [13], which demonstrates differences are substantial [14], and he nevertheless concluded he would find it wholly plausible that Ippolit is a "reverse-engineered Rybka with many changes" in the same forum thread. RobboLito's sentinel [15] Milos Stanisavljevic [16] [17] is proponent of Ippolit's originality, despite his note it used ideas from reverse engineering Rybka 3 [18].
