Tractability results for the Double-Cut-and-Join circular median problem
نویسندگان
چکیده
The circular median problem in the Double-Cut-and-Join (DCJ) distance asks to find, for three given genomes, a fourth circular genome that minimizes the sum of the mutual distances with the three other ones. This problem has been shown to be NP-complete. We show here that, if the number of vertices of degree 3 in the breakpoint graph of the three input genomes is fixed, then the problem is tractable.

Algebraic double cut and join : A group-theoretic approach to the operator on multichromosomal genomes.
Establishing a distance between genomes is a significant problem in computational genomics, because its solution can be used to establish evolutionary relationships including phylogeny. The "double cut and join" (DCJ) model of chromosomal rearrangement proposed by Yancopoulos et al. (Bioinformatics 21:3340-3346, 2005) has received attention as it can model inversions, translocations, fusion and...
متن کاملGenome Halving with Double Cut and Join
The genome halving problem, previously solved by El-Mabrouk for inversions and reciprocal translocations, is here solved in a more general context allowing transpositions and block interchange as well, for genomes including multiple linear and circular chromosomes. We apply this to several datasets and compare the results to the previous algorithm.
متن کاملAn Exact Solver for the DCJ Median Problem
The "double-cut-and-join" (DCJ) model of genome rearrangement proposed by Yancopoulos et al. uses the single DCJ operation to account for all genome rearrangement events. Given three signed permutations, the DCJ median problem is to find a fourth permutation that minimizes the sum of the pairwise DCJ distances between it and the three others. In this paper, we present a branch-and-bound method ...
متن کاملAlgorithms for sorting unsigned linear genomes by the DCJ operations
MOTIVATION The double cut and join operation (abbreviated as DCJ) has been extensively used for genomic rearrangement. Although the DCJ distance between signed genomes with both linear and circular (uni- and multi-) chromosomes is well studied, the only known result for the NP-complete unsigned DCJ distance problem is an approximation algorithm for unsigned linear unichromosomal genomes. In thi...
متن کاملSCJ: A Variant of Breakpoint Distance for Which Sorting, Genome Median and Genome Halving Problems Are Easy
The breakpoint distance is one of the most straightforward genome comparison measures. Surprisingly, when it comes to define it precisely for multichromosomal genomes with both linear and circular chromosomes, there is more than one way to go about it. In this paper we study Single-Cut-or-Join (SCJ), a breakpoint-like rearrangement event for which we present linear and polynomial time algorithm...
