Best practices and boundary conditions
The idea of a memory test or of a test of academic achievement is often circumscribed. Tests within the classroom are recognized as important for the assignment of grades, and tests given for academic assessment or achievement have increasingly come to determine the course of children's lives: score well on such tests and you advance, are placed in more challenging classes, and attend better sc...
متن کاملBest-First Minimax Search
We describe a very simple selective search algorithm for two-player games, called best-first minimax. It always expands next the node at the end of the expected line of play, which determines the minimax value of the root. It uses the same information as alpha-beta minimax, and takes roughly the same time per node generation. We present an implementation of the algorithm that reduces its space ...
متن کاملRecursive Best-First Search with Bounded Overhead
There are two major paradigms for linear-space heuristic search: iterative deepening (IDA*) and recursive best-first search (RBFS). While the node regeneration overhead of IDA* is easily characterized in terms of the heuristic branching factor, the overhead of RBFS depends on how widely the promising nodes are separated in the search tree, and is harder to anticipate. In this paper, we present ...
متن کاملUsing Lookaheads with Optimal Best-First Search
We present an algorithm that exploits the complimentary benefits of best-first search (BFS) and depth-first search (DFS) by performing limited DFS lookaheads from the frontier of BFS. We show that this continuum requires significantly less memory than BFS. In addition, a time speedup is also achieved when choosing the lookahead depth correctly. We demonstrate this idea for breadth-first search ...
متن کاملIs Best First Search Really Best?
Of the many minimax algorithms, SSS* consistently searches the smallest game trees. Its success can be attributed to the accumulation and use of information acquired while traversing the tree, allowing a best first search strategy. The main disadvantage of SSS* is its excessive storage requirements. This paper describes a class of search algorithms which, though based on the popular alpha-beta ...
