void	core::conformation::find_neighbors_octree (utility::pointer::shared_ptr< utility::graph::UpperEdgeGraph< Vertex, Edge > > point_graph, core::Real neighbor_cutoff, Strategy strategy)
	Finds the residue neighbors efficiently using an octree-like spatial sort. More...
template<class Vertex , class Edge >
void	core::conformation::find_neighbors_3dgrid (utility::pointer::shared_ptr< utility::graph::UpperEdgeGraph< Vertex, Edge > > point_graph, core::Real neighbor_cutoff)
	Create a 3D grid of points. O(N^3). For "spherical" conformations, Theta(N). Speeds neighbor detection in abinitio by a factor of 2. Definition: Spherical = span of x,y and z all O(N**1/3). Note circularity. Adendum: if the 3D grid used a list of point indices instead of a vector, then this would be Theta(N) for spherical conformations; however, with a vector, this is O(NlgN). With the additional assumption that each cube contains O(1) points, then this implementation is O(N). Such an assumption is unneccessary in the list implementation. More...
