We were interested in the shortest path a ship could take through a network of about 13,000 route points. Algorithms based on -graph theory, such as A* search, provide an optimal solution to this -problem. Therefore, it was useful to model the set of route points as a graph. +graph theory, such as A* search, provide optimal solutions to such problems. +In other words, the set of route points lends itself well to a model based on +graphs. A graph is a finite set of vertices, and a subset of vertex pairs (edges). Edges can have weights. In the case of vessel tracking, the route points form |
