Finding Cores of Limited Length
In this paper we consider the problem of nding a core of limited length in a tree. A core is a path, which minimizes the sum of the distances to all nodes in the tree. This proble...

Maximizing Non-Linear Concave Functions in Fixed Dimension
Consider a convex set P in IRd and a piecewise polynomial concave function F: P IR. Let A be an algorithm that given a point x IRd computes F(x) if x P, or returns a concave po...

Necklaces, Convolutions, and X + Y
We give subquadratic algorithms that, given two necklaces each with n beads at arbitrary positions, compute the optimal rotation of the necklaces to best align the beads. Here ali...
