BGL: filtering (newbee)
Hi I have a question about graph filtering. My problem is that I would like to filter all edges from a graph g with weight less than 0.01 and all vertices which only has out edges with a weight less than 0.01 The filtering of the edges is show in the documentation. However I have problems with filtering the vertices. Can anyone help? Thanks Line

The filtering of vertices can be done exactly the same way as with the
edges. Just exchange the string edge with vertex in the example given in the
docs of filtered graph. Then create the filtered graph with:
//edge_filter
positive_edge_weight<EdgeWeightMap> edge_filter(get(edge_weight, g));
//vertex_filter
positive_vertex_weight<VertexWeightMap> vertex_filter(get(vertex_weight, g));
filtered_graph
