Webproblem is to ﬁnd a closed walk visiting each vertex odd number of times, instead of exactly once. Note that a closed walk is allowed to use an edge more than once in the problem. Thus, another version of the problem which is to ﬁnd a closed walk visiting each vertex EVEN number of times is trivial; ﬁnd a spanning tree and trace it twice.
