In one embodiment, a vertex to remaining each vertex is calculated using signal source shortest path (Dijkstra) algorithm
Shortest path first, solution is shortest route problem in digraph.It is mainly characterized by centered on starting point outward layer by layer
Extension, until expanding to terminal.
Dijkstra's algorithm states an array dis using a kind of strategy of greed to save source point to each top
The set on the vertex of shortest path: T, when initial, the path weight value of origin s has been found in the shortest distance of point and a preservation
It is assigned to 0 (dis [s]=0).If there is the side (s, m) that can directly reach for vertex s, dis [m] is set as w (s, m), together
When the path length on every other (s cannot be reached directly) vertex is set as infinitely great.When initial, set T only has vertex s.
Then, selecting minimum value from dis array, then the value is exactly shortest path of the source point s to the corresponding vertex of the value, and
And the point is added in T, a vertex is completed at this time, then, it would be desirable to look at whether the vertex being newly added can reach
Other vertex and looking at reached by the vertex other points path length it is whether more direct than source point reach it is short, if so, that
Just replace value of these vertex in dis.
Then, minimum value and from dis is found out, above-mentioned movement is repeated, until containing all vertex of figure in T.
In one embodiment, using minimum spanning tree (Kruskal) algorithm.The basic thought of Kruskal algorithm be with
While being leading position, when the MINIMUM WEIGHT of currently available (selected cannot constitute circuit) being selected to plant always.So Kruskal is calculated
The first step of method is to sort to all sides according to sequence from small to large, next successively investigates each side from small to large
(u, v).
The specific implementation process is as follows:
(1) setting one has the connected network on n vertex as G (V, E), an only n vertex is initially first constructed, without side
Unconnected graph T={ V, empty }, each one lattice connected component of vertex self-contained in figure.
(2) when selecting a side planted with MINIMUM WEIGHT in E, if two vertex on the side fall in different connected components
On, then this side is added in T；Otherwise, i.e. two vertex of this edge are fallen on same connected component, then are cast out this side
(hereafter never selecting this edge) reselects a power and plants the smallest side.
(3) it so repeats down, until all vertex are until on same connected component.
