This paper deals with an alternative form of temporal CSPs; the number of variables is relatively small and the domains are large collections of intervals. Such situations may arise in temporal databases where several types of queries can be modeled and processed as CSPs. For these problems, systematic CSP algorithms can take advantage of temporal indexing to accelerate search. Directed search versions of chronological backtracking and forward checking are presented and tested . Our results show that indexing can drastically improve search performance.","doi":null,"url":"https://ijcai.org/proceedings/1999/63","pdf":"https://ijcai.org/proceedings/1999/0063.pdf","markdown":"https://ijcai.org/proceedings/1999/63.md","bibtex":"https://ijcai.org/proceedings/1999/bibtex/63","volume":{"slug":"1999","title":"Proceedings of the Sixteenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1999","url":"https://ijcai.org/proceedings/1999/","year":1999,"location":"Stockholm, Sweden","dates":"","editors":"Thomas Dean","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Constraint Satisfaction","track":"Constraint Satisfaction","number":63,"pages":{"first":436,"last":440},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
