In this note, we give a proof that several vertex ordering problems can be solved in O*(2n) time and O*(2n) space, or in O*(4n) time and polynomial space. The algorithms generalize algorithms for the Travelling Salesman Problem by Held and Karp (J. Soc. Ind. Appl. Math. 10:196-210, 1962) and Gurevich and Shelah (SIAM J. Comput. 16:486-502, 1987). We survey a number of vertex ordering problems to which the results apply.
