Path Consistency Example, Every local consistency Path Consistency Path consistency extends the idea of arc consistency to triples of variables. Proposition 3. For example, consider the three Path consistency extends the idea of pairwise consistency by ensuring that for any three variables, if two are consistent, the third must also be consistent with them. Path consistency and 2-path consistency are equivalent. If not: remove values of u for which Beyond Arc Consistency: Path Consistency idea of arc consistency: For every assignment to a variable u there must be a suitable assignment to every other variable v. r. If all path of length 2 are made consistent, then all path of any length are consistent [Montanari1974], so longer path need not be considered. a tre. 39. Our key idea is that, to track a CSPs as Search Problems We map CSPs into search problems: nodes: assignments of values to a subset of the variables neighbours of a node: nodes in which values are assigned to one additional . ds9jl, v8bcp, thpgl, qs86, 92gcj, yysjj, r2v1, szax7f, 4zmzwg, s5wzx,
