Journal ArticleDOI
A Sufficient Condition for Backtrack-Free Search
TL;DR: A relationship involving the structure of the constraints is described which characterizes to some degree the extreme case of mimmum backtracking and a concept called "width," which may provide some guidance in the representation of constraint satisfaction problems and the order in which they are searched.
Journal ArticleDOI
The complexity of some polynomial network consistency algorithms for constraint satisfaction problems
TL;DR: The time complexity of several node, arc and path consistency algorithms is analyzed and it is proved that arc consistency is achievable in time linear in the number of binary constraints.
Journal ArticleDOI
Partial constraint satisfaction
TL;DR: A general model of partial constraint satisfaction is proposed and standard backtracking and local consistency techniques for solving constraint satisfaction problems can be adapted to cope with, and take advantage of, the differences between partial and complete constraint satisfaction.
Journal ArticleDOI
Synthesizing constraint expressions
TL;DR: An algorithm is developed that can achieve any level of consistency desired, in order to preprocess the problem for subsequent back track search, or to function as an alternative to backtrack search by explicitly determining all solutions.
Proceedings Article
Contradicting conventional wisdom in constraint satisfaction
Daniel Sabin,Eugene C. Freuder +1 more
TL;DR: Evidence contradicting both pieces of conventional wisdom is presented, and renewed consideration of an approach which fully maintains arc consistency during backtrack search is suggested.
