an [[UCI]] compliant, experimental [[Open Source Engines|open source chess engine]] by [[Antonio Torrecillas]], written in [[Cpp|C++]] and licensed under the [[Free Software Foundation#GPL|GNU General Public License]]. Rocinante was developed as test bed for [[Best-First|best-first]] search algorithms, notably [[B*|PB*]] by [[Hans Berliner]] and [[Chris McConnell]] <ref>[[Hans Berliner]], [[Chris McConnell]] (**1995**). //B* Probability Based Search.// [[Carnegie Mellon University]] Computer Science research report</ref>, and was first released in August 2009 <ref>[[http://www.talkchess.com/forum/viewtopic.php?t=29360|engine Rocinante is available]] by [[Antonio Torrecillas]], [[CCC]], August 12, 2009</ref>. Rocinante **2.0**, released in May 2012, was a rewrite changing the board representation from [[Bitboards|bitboards]] to [[Mailbox|mailbox]], and further added a [[https://en.wikipedia.org/wiki/Greedy_algorithm|greedy]] [[Monte-Carlo Tree Search]] without random playouts, dubbed [[MCαβ]], as additional search algorithm <ref>[[http://www.talkchess.com/forum/viewtopic.php?t=41730|MCTS without random playout?]] by [[Antonio Torrecillas]], [[CCC]], January 01, 2012</ref>. Both, MCαβ and PB* Rocinante may be configured to apply a shallow [[Alpha-Beta|alpha-beta search]] as a replacement for the [[Evaluation|static evaluation]] <ref>[[http://www.talkchess.com/forum/viewtopic.php?t=43895|Rocinante 2.0 Release]] by [[Antonio Torrecillas]], [[CCC]], May 30, 2012</ref>.

=Etymology=
[[https://en.wikipedia.org/wiki/Rocinante|Rocinante]] is [[https://en.wikipedia.org/wiki/Don_Quixote|Don Quixote's]] horse in the novel //[[https://en.wikipedia.org/wiki/Don_Quixote|The Ingenious Gentleman Don Quixote of La Mancha]]// by [[https://en.wikipedia.org/wiki/Miguel_de_Cervantes|Miguel de Cervantes]]. In many ways, Rocinante is not only Don Quixote's horse, but also his [[https://en.wikipedia.org/wiki/Double|double]]: like Don Quixote, he is awkward, past his prime, and engaged in a task beyond his capacities. Rocín in [[https://en.wikipedia.org/wiki/Spanish_language|Spanish]] means a [[https://en.wikipedia.org/wiki/Draft_horse|work horse]] or low-quality horse, but can also mean an illiterate or rough man. The name is a complex pun. In Spanish, [[https://en.wiktionary.org/wiki/ante|ante]] has several meanings and can function as a standalone word as well as a [[https://en.wikipedia.org/wiki/Suffix|suffix]]. One meaning is "before" or "previously". Another is "in front of". As a suffix, [[https://en.wiktionary.org/wiki/-ante#Spanish|-ante]] in Spanish is [[httpa://en.wikipedia.org/wiki/Adverbial|adverbial]]; rocinante refers to functioning as, or being, a rocín. "Rocinante," then, follows Cervantes' pattern using ambiguous, multivalent words, common throughout the novel <ref>[[https://en.wikipedia.org/wiki/Rocinante|Rocinante from Wikipedia]]</ref>.
