In contrast to this old result, our NP-hardness reductions are substantially simpler..As a positive result we show that the Fréchet distance between polygons with one hole can be computed in polynomial time.

Der historische Roman und seine Formen,the running-time is .(.log. + (. + |.|).)..This is an extension of an algorithm by Erickson and Whittlesey [., 1038–1046 (2005)], which computes a shortest cut graph with a single given vertex. Moreover, our proof is simpler and also reveals that the algorithm actually computes a minimum-weight basis of some matroid.

A 25/17-Approximation Algorithm for the Stable Marriage Problem with One-Sided Tieswhen preference lists of one side do not contain ties, and it cannot be approximated within . unless P=NP. However, even under this restriction, the best known approximation ratio is still 1.5. In this paper, we improve it to ..

Pairing Heaps with Costless Meldre . is the size of the priority queue at the time the operation is performed. These bounds are the best known for any self-adjusting heap, and match the lower bound established by Fredman for a family of such priority queues. Moreover, our structure is even simpler than that in [1].
