    Input: a directed grid graph G, a set of target points S, and an integer k Output: true if there is a path through G that visits all points in S using at most k left turns A grid graph is a graph where the vertices are at integer coordinates from 0,0 to n,n. (So 0,0,  0,1,  0,2,  ...0,n,  1,0,  etc.) Also, all edges are between vertices at distance 1. (So 00->01, 00->10, but not 00 to any other vertex....

    Say that we have an undirected graph G(V, E) and a pair of vertices s, t and a vertex v that we call a a desired middle vertex . We wish to find out if there exists a simple path (every vertex appears at most once) from s to t that goes via v. Create a flow network by making v a source. Add a new vertex Z as a sink. Join s, t with two directed edges of capacity...
