Zigzag persistent homology in matrix multiplication time
We present a new algorithm for computing zigzag persistent homology, an algebraic structure which encodes changes to homology groups of a simplicial complex over a sequence of sim...

Two Dimensional Parameterized Matching
Two equal length strings, or two equal sized two-dimensional texts, parameterize match (p-match) if there is a one-one mapping (relative to the alphabet) of their characters. Two-...

On the vertices of the k-additive core
The core of a game v on N, which is the set of additive games dominating v such that (N) = v(N), is a central notion in cooperative game theory, decision making and in combinator...

A specimen MPI application: N-Queens in parallel
: The generalized problem of placing n queens on an n-by-n board provides an "embarrassingly parallel" problem for parallel solution. This paper expands on the discussion...
