چکیده

Given a polygonal curve P , a pointset S, and an ε > 0, we study the problem of finding a polygonal curve Q whose vertices are from S and has a Fréchet distance less or equal to ε to curve P . In this problem, Q must visit every point in S and we are allowed to reuse points of pointset in building Q. First, we show that this problem in NP-Complete. Then, we present a polynomial time algorithm for a special cases of this problem, when P is a convex polygon.
