Improved output-sensitive quantum algorithms for Boolean matrix multiplication
We present new quantum algorithms for Boolean Matrix Multiplication in both the time complexity and the query complexity settings. As far as time complexity is concerned, our resu...

On the Topological Complexity of Weakly Recognizable Tree Languages
We show that the family of tree languages recognized by weak alternating automata is closed by three set theoretic operations that correspond to sum, multiplication by ordinals <...

Multiple Genome Alignment: Chaining Algorithms Revisited
Given n fragments from k > 2 genomes, we will show how to find an optimal chain of colinear non-overlapping fragments in time O(n logk−2 n log log n) and space O(n logk−2 n...

Simplified digital holographic reconstruction using statistical methods
For reconstructing a complex object wavefront from digital holograms, we propose a new penalized-likelihood approach based on the measurement statistics and edge-preserving regula...
