Minimizing Average Shortest Path Distances via Shortcut Edge Addition
We consider adding k shortcut edges (i.e. edges of small fixed length δ ≥ 0) to a graph so as to minimize the weighted average shortest path distance over all pairs of vertices...

On Completing Latin Squares
We present a (2 3 − o(1))-approximation algorithm for the partial latin square extension (PLSE) problem. This improves the current best bound of 1 − 1 e due to Gomes, Regis, an...

Visualization of higher order singularities in vector fields
We present an algorithm for the visualization of vector field topology based on Clifford algebra. It is the first method allowing the detection of higher order singularities. Th...
