UIB-2005-03 Constrained Ordering
Autoren: Walter Guttmann, Markus Maucher
We investigate the problem of finding a total order of a finite set that satisfies various local ordering constraints. Depending on the admitted constraints, we provide an efficient algorithm or prove NP-completeness. To this end, we define a reduction technique and discuss its properties. Key words: total ordering, NP-completeness, computational complexity, betweenness, cyclic ordering, topological sorting.
