An Exact Algorithm for TSP in Degree-3 Graphs Via Circuit Procedure and Amortization on Connectivity Structure

The paper presents an O ∗ ( 1 . 2312 n ) -time and polynomial-space algorithm for the traveling salesman problem in an n -vertex graph with maximum degree 3. This improves all previous time bounds of polynomial-space algorithms for this problem. Our algorithm is a simple branch-and-search algorithm...
