Balanced Randomized Tree Splitting with Applications to Evolutionary Tree Constructionsproximation algorithm for the maximum agreement subtree problem for binary trees for which the maximum number of leaves in an optimal solution is large. We also present new lower bounds for the problem of constructing an evolutionary tree from experiments and for the problem of constructing a tree from an ultrametric distance matrix.

On the Hardness of Permanent The assumed algorithm can also be a probabilistic polynomial time algorithm. Our result is essentially the best possible based on any black box assumption of permanent solvers, and is a simultaneous improvement of the results of Gemmell and Sudan [.], Feige and Lund [.] as well as Cai and Hemachandra [.], and Toda (see [.]).
