Geometric Scheduling of 2-D UET-UCT Uniform Dependence Loops
Finding an optimal time schedule is one of the primary tasks in the area of parallelizing uniform dependence loops. Due to the existence of dependence vectors, the index space of such a loop, is split into subspaces of points that can be executed at different time instances. The geometric representation of these sets form certain polygonal shapes called patterns, with special attributes and cha...
متن کاملASAP-UCT: Abstraction of State-Action Pairs in UCT
Monte-Carlo Tree Search (MCTS) algorithms such as UCT are an attractive online framework for solving planning under uncertainty problems modeled as a Markov Decision Process. However, MCTS search trees are constructed in flat state and action spaces, which can lead to poor policies for large problems. In a separate research thread, domain abstraction techniques compute symmetries to reduce the ...
متن کاملOGA-UCT: On-the-Go Abstractions in UCT
Recent work has begun exploring the value of domain abstractions in Monte-Carlo Tree Search (MCTS) algorithms for probabilistic planning. These algorithms automatically aggregate symmetric search nodes (states or state-action pairs) saving valuable planning time. Existing algorithms alternate between two phases: (1) abstraction computation for computing node aggregations, and (2) modified MCTS ...
متن کاملTo UCT, or not to UCT? (Position Paper)
Monte-Carlo search is successfully used in simulation-based planning for various large-scale sequential decision problems, and the UCT algorithm (Kocsis and Szepesvári 2006) seems to be the choice in most (if not all) such recent success stories. Based on some recent discoveries in theory and empirical analysis of Monte-Carlo search, here we argue that, if online sequential decision making is y...
متن کاملOn the Parallelization of UCT
We present three parallel algorithms for UCT. For 9×9 Go, they all improve the results of the programs that use them against GNU GO 3.6. The simplest one, the single-run algorithm, uses very few communications and shows improvements comparable to the more complex ones. Further improvements may be possible sharing more information in the multiple-runs algorithm.
