Complexity and Enumeration in Models of Genome Rearrangement
In this paper, we examine the computational complexity of enumeration in certain genome rearrangement models. We first show that the Pairwise Rearrangement problem in the Single Cut-and-Join model (Bergeron, Medvedev, Stoye, J. Comput. Biol. 2010) is #-complete under polynomial-time Turing reductions. Next, we show that in the Single Cut or Join model (Feijao Meidanis, IEEE ACM Trans. Comp. Biol. Bioinf. 2011), the problem of enumerating all medians (#Median) is logspace-computable (), improving upon the previous polynomial-time () bound of Miklós Smith (RECOMB 2015).
