Detailed Description

template<typename graph_t>
class negative_density< graph_t >

For use in networks with negative edge weights.

simple_density and complex_density will not work with negative edges. Negative_density will only work with negative edges. (Not entirely true, the communities are senseless if used in an all-positive network)

Member Function Documentation

template<typename graph_t >

double negative_density< graph_t >::operator()	(	typename graph_t::edge_name_t	win,
		typename graph_t::edge_name_t	wout,
		lui	k
	)		const [inline, virtual]

Calculates a density based on the above numbers.

Parameters:

win	Sum of weights of edges with both endpoints in cluster
wout	Sum of weights of edges with exactly one endpoint in cluster
k	Size of the cluster

Returns:

(win-wout)/k

Implements density< graph_t >.
