Counting consistent phylogenetic trees is #P-complete.

Bordewich, M. and Semple, C. and Talbot, J. (2004) 'Counting consistent phylogenetic trees is #P-complete.', Advances in mathematics., 33 (2). pp. 416-430.


Reconstructing phylogenetic trees is a fundamental task in evolutionary biology. Various algorithms exist for this purpose, many of which come under the heading of `supertree methods'. These methods amalgamate a collection Ρ of phylogenetic trees into a single parent tree. In this paper, we show that, in both the rooted and unrooted settings, counting the number of parent trees that preserve all of the ancestral relationships displayed by the phylogenetic trees in Ρ is #P-complete.
