Aug 30, 2016. Given a set of cities (i.e., points, or vertices), the goal of the TSP is to find a minimum cost circuit (or cycle, or tour) that visits all the points. More formally, the. a vertex already has even degree, why are we doubling all of its outgoing edges, and thus increasing our cost? Consider the example in Figure 5.
