While FSSS-Minimax is guaranteed to never expand more leaves than alpha-beta, the best-first approach comes at a cost in terms of memory requirements as well as computational cost. We modify a rollout-based method, FSSS, to allow for use in game-tree search and show it outprunes alpha-beta both empirically and formally. In this paper, we show that trajectories can be used to prune more aggressively than classical alpha-beta search. Brand Coaching + Business Development for purposeful professionals and growing organizations. Game-playing programs based on Monte-Carlo rollouts methods such as “ UCT” have proven remarkably effective at using information from trajectories to make state-of-the-art decisions at the root. I am Ari Weinstein and I cofounded DeskConnect, Inc., a Delaware company that is dedicated to creating software suites including and Workflow.is. The fundamental operation in rollout-based tree search is the generation of trajectories in the search tree from root to leaf. Recently, rollout-based planning and search methods have emerged as an alternative to traditional tree-search methods. FSSS-Minimax only visits parts of the tree that alpha-beta visits, and is in terms of related work similar to the Score Bounded Monte-Carlo Tree Search introduced by Tristan Cazenave and Abdallah Saffidine. In their paper Rollout-based Game-tree Search Outprunes Traditional Alpha-beta, along with Sergiu Goschin and his advisor Michael Littman, Weinstein introduce the rollout-based FSSS (Forward-search sparse sampling) applied to game-tree search, outpruning alpha-beta both empirically and formally. ![]()
