The Unreasonable Success of Local Search: Geometric Optimization [PDF]

open access: yes, 2015
What is the effectiveness of local search algorithms for geometric problems in the plane? We prove that local search with neighborhoods of magnitude $1/\epsilon^c$ is an approximation scheme for the following problems in the Euclidian plane: TSP with ...
