Phylogenetic trees in ACL2
Biologists studying the evolutionary relationships between organisms use software packages to solve the computational problems they encounter. Several of these problems involve th...

Complexity Theory Made Easy
In recent years generalized acceptance criteria for different nondeterministic computation models have been examined. Instead of the common definition where an input word is said...

On reconstructing species trees from gene trees in term of duplications and losses
This paper studies various properties of the least common ancestors mapping, the duplication and mutation costs, and the complexity of nding a species tree from gene trees.

Reconstructing Evolution of Natural Languages: Complexity and Parameterized Algorithms
In a recent article, Nakhleh, Ringe and Warnow introduced perfect phylogenetic networks--a model of language evolution where languages do not evolve via clean speciation--and form...

Rounds vs. Queries Tradeoff in Noisy Computation
: We show that a noisy parallel decision tree making O(n) queries needs (log n) rounds to compute OR of n bits. This answers a question of Newman [IEEE Conference on Computational ...
