Fixed-Parameter Algorithms for Kemeny Scores
The Kemeny Score problem is central to many applications in the context of rank aggregation. Given a set of permutations (votes) over a set of candidates, one searches for a “con...

Fixed-Parameter Algorithms for Protein Similarity Search Under mRNA Structure Constraints
Abstract. In the context of protein engineering, we consider the problem of computing an mRNA sequence of maximal codon-wise similarity to a given mRNA (and consequently, to a give...

Fixed Parameter Tractable Alignment of RNA Structures Including Arbitrary Pseudoknots
We present an algorithm for computing the edit distance of two RNA structures with arbitrary kinds of pseudoknots. A main benefit of the algorithm is that, despite the problem is N...

Bypassing Combinatorial Protections: Polynomial-Time Algorithms for Single-Peaked Electorates
For many election systems, bribery (and related) attacks have been shown NP-hard using constructions on combinatorially rich structures such as partitions and covers. It is import...

Bit-parallel Computation of Local Similarity Score Matrices with Unitary Weights
Abstract. Local similarity computation between two sequences permits detecting all the relevant alignments present between subsequences thereof. A well-known dynamic programming al...
