The time-dependent traveling salesman problem (TDTSP) is a variant of TSP
with time-dependent edge costs. We study some restrictions of
TDTSP where the number of edge cost changes are limited. We find
competitive ratios for online versions of TDTSP. From these we
derive polynomial time approximation algorithms for graphs with
edge costs one and two. In addition, we present an approximation
algorithm for the orienteering problem with edge costs one and two.
