1. A method comprising:

  • representing a network using a graph, the graph comprising a plurality of vertices and a plurality of edges, the plurality of vertices comprising a source vertex, a destination vertex and a vertex u, the plurality of edges linking corresponding adjacent pairs of the plurality of vertices; and

    determining a minimum cost path in the graph from the source vertex to the destination vertex, wherein the vertex u is in the minimum cost path, and wherein an edge from the vertex u in the minimum cost path introduces an additional capital expenditure cost that is dependent on how the minimum cost path traverses from the source vertex to the vertex u.
