Othello Is Solved? (arxiv.org)

Article summary

A recent paper claims to have solved the game of Othello, proving that perfect play by both players leads to a draw. The solution is based on a computational proof, which analyzed the game's vast number of possible positions. The paper's findings have implications for the game's competitive scene and the development of Othello software. The solution is considered a 'weak' solution, meaning it demonstrates perfect play from the initial state but does not provide a perfect strategy for all possible game states.

What commenters say

• Solving a game like Othello renders human competitions moot because the optimal moves can be looked up, reducing the challenge to mere memorization.
• A solved game can still be interesting and challenging for humans, as they can focus on executing the perfect strategy and adapting to deviations.
• The solution to Othello is 'weak', meaning it only guarantees a draw from the initial position, and does not provide a perfect strategy for all possible game states.
• Competitive games like chess and Othello are often played with a focus on not losing rather than winning, which can lead to a high percentage of draws at the top level.
• Introducing randomization or limiting computational power could make competitive games more interesting and challenging.
• A game being 'solved' does not necessarily mean that humans can easily memorize and execute the perfect strategy, as the number of possible positions can be extremely large.
• The concept of a 'solved' game is nuanced, with different types of solutions, such as 'weak', 'strong', and 'ultra-weak', each with its own implications for the game.
• The solution to Othello has implications for the development of game-playing software and the potential for future breakthroughs in other games.
