It is here that high-level chess studies provide an important mechanism for testing the ability of a given AI algorithm. Given the enormous number of possible paths of play (the Shannon number), the use of search methods and the depth of the algorithm become important computational aspects. In doing so, the algorithm offers an optimal path of play. This framework, together with the use of deep neural networks to model the value and policy functions, provides a solution for maximising the probability of winning the chess game. On the theoretical side, we describe a central tool for solving dynamic stochastic programming problems: the Bellman equation. We further discuss which algorithms possess greater potential in the field of AGI by reviewing their ability to generalize to different domains. By comparing this with machine performance, we can better assess the state of current progress on the long road to building AGI. Historical records provide insight into human performance on PlaskettвЂ™s Puzzle. famously claimed that the rules of chess could be determined from empirical observation, a central tenet of artificial general intelligence. ДЄrtificial general intelligence (AGI) is the ability of an algorithm to achieve human intelligence in a multitude of tasks. Stockfish heavily relies on alpha-beta search, which has been used to verify neural networksвЂ™ robustness to adversarial attacks. Researchers have since used this idea to construct procedures for chemical synthesis and optimize the dynamics of quantum systems. LCZero and its predecessor, AlphaZero, use neural networks to guide a Monte Carlo tree search. Our work suggests that building a chess engine with a broad and efficient search may still be the most robust approach.Д¬hess engine research has implications for problems requiring large-scale tree search. We find that Stockfish solves the puzzle with much greater efficiency than LCZero. We discuss the implications of their performance for both end users and the artificial intelligence community as a whole. We evaluate the performance of Stockfish 14 and Leela Chess Zero (LCZero) on PlaskettвЂ™s Puzzle. The advent of powerful computer chess engines enables us to revisit chess studies where the highest level of tactics and accuracy are required. Though the puzzle was initially created by a Dutch composer, it achieved notoriety in 1987 when English grandmaster Jim Plaskett posed the problem at a chess tournament, stumping all players except Mikhail Tal. There are many features of PlaskettвЂ™s Puzzle that make it particularly hard-not just the depth required (15 moves) but also the use of underpromotion (a particularly counterintuitive kind of move in chess) and subtle tactical strategies. The endgame is the final phase of a chess game. We choose to analyse how chess engines respond to PlaskettвЂ™s Puzzle, one of the most well-known endgame studies in history. As such, they provide a good benchmark for AI studies. They are a notoriously difficult kind of puzzle, involving detailed calculations and tactical motifs. Chess studies originally became popular in the 19th century. There are various schools of thought in chess composition, each of which placing different emphasis on the complexity of problems. You may not be able to work out the answers, but in theory, there must be a solution, a right procedure in any position-John von Neumann Chess is a well-defined form of computation. To conclude, we discuss the implications of our work on artificial intelligence (AI) and artificial general intelligence (AGI), suggesting possible avenues for future research.Д¬hess is not a game. On the theoretical side, we describe how BellmanвЂ™s equation may be applied to optimize the probability of winning. Drawing inspiration from how humans solve chess problems, we ask whether machines can possess a form of imagination.

We examine the algorithmic differences between the engines and use our observations as a basis for carefully interpreting the test results. Our experiments show that Stockfish outperforms LCZero on the puzzle. We use PlaskettвЂ™s Puzzle, a famous endgame study from the late 1970s, to compare the two engines. Two of the leading chess engines, Stockfish and Leela Chess Zero (LCZero), employ significantly different methods during play. We find that they can serve as a tool for testing machine ability as well. Endgame studies have long served as a tool for testing human creativity and intelligence.
