Rocinante

an UCI compliant, experimental open source chess engine by Antonio Torrecillas, written in C++ and licensed under the GNU General Public License. Rocinante was developed as test bed for best-first search algorithms, notably PB* by Hans Berliner and Chris McConnell, and was first released in August 2009. Rocinante **2.0**, released in May 2012, was a rewrite changing the board representation from bitboards to mailbox, and further added a [|greedy] Monte-Carlo Tree Search without random playouts, dubbed MCαβ, as additional search algorithm. Both, MCαβ and PB* Rocinante may be configured to apply a shallow alpha-beta search as a replacement for the static evaluation. Rocinante source can be compiled to run under various platforms and operating systems such as Windows, Linux and Android. || toc =Etymology= [|Rocinante] is [|Don Quixote's] horse in the novel //[|The Ingenious Gentleman Don Quixote of La Mancha]// by [|Miguel de Cervantes]. In many ways, Rocinante is not only Don Quixote's horse, but also his [|double]: like Don Quixote, he is awkward, past his prime, and engaged in a task beyond his capacities. Rocín in [|Spanish] means a [|work horse] or low-quality horse, but can also mean an illiterate or rough man. The name is a complex pun. In Spanish, [|ante] has several meanings and can function as a standalone word as well as a [|suffix]. One meaning is "before" or "previously". Another is "in front of". As a suffix, [|-ante] in Spanish is adverbial; rocinante refers to functioning as, or being, a rocín. "Rocinante," then, follows Cervantes' pattern using ambiguous, multivalent words, common throughout the novel.
