==Popeye==

Popeye is a chess problem-solving software accommodating many fairy chess rules and able to investigate set play and tries. 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, cf. {{GitHub|https://github.com/thomas-maeder/popeye}}. Since its origin, Popeye was designed as a general-purpose, extensible tool for checking fairy and heterodox chess problems.<ref>{{cite web|title=A short history of Popeye|year=2012|website=Julia’sFairies|access-date=16 November 2018|first=Thomas|last=Brand|url=http://juliasfairies.com/software/popeye/history-of-popeye/}}</ref><ref>{{cite magazine|first=Thomas|last=Brand|magazine=Die Schwalbe|issue=104 |date=April 1987|pages=215-216215–216|title=Popeye, eine eierlegende Wollmilchsau?}}</ref> The original author of Popeye was Philippe Schnoebelen who wrote it in [[Pascal (programming language)|Pascal]] under [[MS-DOS]] around 1983-84. In 1986 the code was 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 the [[C (programming language)|C programming language]], 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.
