Ključnе rеči: | constraint satisfaction problembounded widthcongruence distributivity | Dаtum izdаvаnjа: | 2009 | Čаsоpis: | Algebra Universalis | Sažetak: | We prove that the constraint languages invariant under a short sequence of Jónsson terms (containing at most three non-trivial ternary terms) are tractable by showing that they have bounded width. This improves a previous result by Kiss and Valeriote and presents some evidence that the Larose–Zádori conjecture holds in the congruence-distributive case. | URI: | https://open.uns.ac.rs/handle/123456789/28511 | ISSN: | 0002-5240 1420-8911 |
