Query: Finding Approximately Convex Ropes in the Plane   The convex rope problem is to find a counterclockwise or clockwise convex
rope starting at the vertex a and ending at the vertex b of a simple polygon P,
where a is a vertex of the convex hull of P and b visible from infinity. The
convex rope mentioned is the shortest path joining a and b that does not enter
the interior of P. In this paper, the problem is reconstructed as the one of
finding such shortest path in a simple polygon and solved by the method of
multiple shooting. We then show that if the collinear condition of the method
holds at all shooting points, then these shooting points form the shortest
path. Otherwise, the sequence of paths obtained by the update of the method
converges to the shortest path. The algorithm is implemented in C++ for
numerical experiments.
