Optimal Covering Tours with Turn Costs
Esther M. Arkin, Michael A. Bender, Erik D. Demaine +3
We give the first algorithmic study of a class of ``covering tour'' problems related to the geometric Traveling Salesman Problem: Find a polygonal tour for a cutter so that it swee…

On the Reflexivity of Point Sets
Esther M. Arkin, Sandor P. Fekete, Ferran Hurtado +4
We introduce a new measure for planar point sets S that captures a combinatorial distance that S is from being a convex set: The reflexivity rho(S) of S is given by the smallest nu…

Esther M. Arkin, Michael A. Bender, Erik D. Demaine +4
We explore the following problem: given a collection of creases on a piece of paper, each assigned a folding direction of mountain or valley, is there a flat folding by a sequence…
