Fixed Parameter Polynomial Time Algorithms for Maximum Agreement and Compatible Supertrees
Consider a set of labels L and a set of trees T = {T (1) , T (2) , . . . , T (k) } where each tree T (i) is distinctly leaf-labeled by some subset of L. One fundamental problem is ...

Minimizing Movement: Fixed-Parameter Tractability
Abstract. We study an extensive class of movement minimization problems which arise from many practical scenarios but so far have little theoretical study. In general, these proble...

Colored Hypergraph Isomorphism is Fixed Parameter Tractable
We describe a fixed parameter tractable (fpt) algorithm for Colored Hypergraph Isomorphism which has running time 2O(b) NO(1) , where the parameter b is the maximum size of the col...

Perfect Path Phylogeny Haplotyping with Missing Data Is Fixed-Parameter Tractable
Abstract. Haplotyping via perfect phylogeny is a method for retrieving haplotypes from genotypes. Fast algorithms are known for computing perfect phylogenies from complete and erro...
