16. Apr. 2024 · Turochamp-1ply is an implementation of Alan Turing and David Champernowne's 1948 TUROCHAMP "paper" chess engine. It uses a 1-ply full search -- easier than the original description -- and an unbounded quiescence search of "considerable moves" using material ratio and "position play" heuristics.
24. Apr. 2021 · Their engine produces nearly the same moves as Turochamp, with some deviations (which they speculate could be due to Turing's own calculation errors). The full reconstructed algorithm is easily available online; a Python implementation can be found here.
They called the program Turochamp, but it popularly became known as “Turing's paper machine. Turing's goal was to make a machine which would play a reasonably good game of chess, i.e. which, confronted with an ordinary chess position, would after two or three minutes of calculation, indicate a passably good legal move. The program introduced the concept of quiescence. Champernowne wrote ...
Turochamp ist der Name eines im Jahre 1948 von Alan Turing und David Champernowne entwickelten Schach-Algorithmus. Er gehörte zu den ersten Schach -Algorithmen der Welt. Funktionsweise. Um den besten Zug in einer Situation zu finden, wer ...
Turochamp incorporated important methods of evaluation, and also the concepts of selectivity and dead position, despite it is unclear how this was "implemented" in the game playing experiments. Champernowne later said 'they were a bit slapdash about all this and must have made a number of slips since the arithmetic was extremely tedious with pencil and paper' [4] .
16. Apr. 2024 · 2024. Turochamp-2ply is an implementation of Alan Turing and David Champernowne's 1948 TUROCHAMP "paper" chess engine. Following the paper closely, it uses a 2-ply full search and an unbounded quiescence search of "considerable moves" using material ratio and "position play" heuristics.
Provenance. Turing’s essay ‘Chess’ was published in the 1953 collection Faster Than Thought, where it formed a section of a chapter entitled ‘Digital Computers Applied To Games’. (Edited by Vivian Bowden, Faster Than Thought is a fascinating survey of the then state of the art in digital computing.)
