List (Program)

Home * Engines * List



List, a chess engine written by Fritz Reul in C. The development started in 2000, and List was first released as WinBoard engine 4.60 in May 2002, and as free native ChessBase engine 5.04 for the Fritz GUI in December 2002.

=Description= List 4.6x is a 32-bit engine operating on 10x8 boards. It uses a recursive fail-soft alpha-beta search with transposition table and quiescence search inside an iterative deepening frame with aspiration, and performs fractional extensions, depth dependent razoring and null move search with fail-high reductions, and IDD. Dann Corbit, who had seen some bit of List's C source code in 2002, on the origin of List's name : The program uses many piece-lists internally, which is where the name comes from, I think. I have seen the evaluation function, which uses separate lists for each piece type.

=WCCC 2003= List participated at the WCCC 2003 in Graz, not represented by its author himself, but by Erdogan Günes. Fritz Reul, being circumvented with examination commitments, did not act appropriate to prove his program was not a clone, as accused due to an official protest during the tournament. As a consequence, List was disqualified after eight of eleven rounds. In 2005, Fritz Reul was rehabilitated by the ICGA, after List's source code was inspected by an expert approved by the ICGA, who stated List was definitely not a clone of any other program, and that it contains some new ideas in chess programming.

=List 5.12= In January 2004, List 5.12 was released as free UCI engine along with Aristarch by Stefan Zipproth. Able to play Chess960, List further played the Chess960CWC 2005.

=Loop List= In October 2005, Fritz Reul's new 32-bit engine dubbed Loop List was released commercially as UCI engine. List and Loop List further evolved to the 32-bit Loop engine as described in chapter 2 Non-Bitboard Architectures of Fritz Reul's Ph.D. thesis New Architectures in Computer Chess.
