Approximating the 2-interval pattern problem

Abstract

We address the problem of approximating the 2-INTERVAL PATTERN problem over its various models and restrictions. This problem, which is motivated by RNA secondary structure prediction, asks to find a maximum cardinality subset of a 2-interval set with respect to some prespecified model. For each such model, we give varying approximation quality depending on the different possible restrictions imposed on the input 2-interval set. © Springer-Verlag Berlin Heidelberg 2005.
