Line 14:
Popeye is chess problem-solving software. Popeye runs from a [[command-line interface]], but it can be used with several operating systems and can be connected to several existing graphical interfaces since it comes with freely available source code in the [[C (programming language)|C programming language]]. Popeye is one of the most exhaustive solving programs.{{citation needed|date=July 2017}} It can solve problems with many fairy pieces and conditions, and can output to [[LaTeX]]. The original author of Popeye was Philippe Schnoebelen who wrote it in [[Pascal (programming language)|Pascal]] under [[MS-DOS]] around 1983-84. The code was later donated in the spirit of the [[free software]] movement. Elmar Bartel, Norbert Geissler, Thomas Maeder, Torsten Linss, Stefan Hoening, Stefan Brunzen, Harald Denker, Thomas Bark and Stephen Emmerson, converted Popeye to C, and now maintain the program.
A good graphic interface "AP WIN" a freeware, for using with Windows XP or Windows 7 has since been developed by Paul H. Wiereyn.<ref>{{cite web |url=http://alybadix.viuhka.fi/apwin/apwin.htm |title=Archived copy |accessdate=2012-08-08 |deadurl=yes |archiveurl=https://web.archive.org/web/20120725065341/http://alybadix.viuhka.fi/apwin/apwin.htm |archivedate=2012-07-25 |df= }}</ref> Using this one can create diagrams and use Popeye for solving problems directly from the diagram.
