Edsel Apostol [1] Edsel G. Apostol,
a Filipino computer engineer and computer game programmer, author of the chess engines Twisted Logic [2], Invictus [3], and along with Sam Hamilton, co-author of Hannibal [4]. His first experience with computer chess was in 2001, when he discovered a program named Ziggurat, and subsequently started computer chess programming in late 2004. He then studied the theories on computer chess programming and started to write his first program using the 0x88 method. He had three rewrites of this and in May 2005 finally adapted rotated bitboards. In May 2007, he started working on a complete rewrite using the magic bitboards method.
Occupation
Edsel has worked as a College Professor for two semesters before deciding to pursue a career in game development. He is currently employed as a software engineer in the Philippine's pioneer Game Development Company, Anino Games, Inc.
