Minimum spanning tree
Selecting the n-1 edge in a connected graph with n vertices, constituting a minimum connected subgraph, and minimizing the sum of the weights on the n-1 edge of the connected subgraph, it is called the minimum spanning tree of the connected network.
For example, a connected network, as shown in the above figure G4, can have multiple spanning trees with different weights combined.

minimum Spanning TreeSelecting the n-1 edge in a connected graph with n vertices, constituting a minimal connected sub-graph, and minimizing the sum of the weights of the n-1 bars in the connected sub-graph, it is called the smallest spanning tree of the connected net.For example, for a connected network as shown in G4, you can have multiple spanning trees with different weights combined.Kruskal Algorithm IntroductionKruskal (Kruskal) algorithm is use
Function dialog box, first select math and trigonometric functions in the "Function category" column of the dialog box, and then select "Sum" in "Function name" and press "OK" to exit.
(2) Select the range of cells you want to calculate. When the function is selected, the function parameter Input dialog box opens. Then click the Collapse Dialog button (that is, the button to the right of the Number1), the dialog disappears, then select the range of cells, select the method (click C4 Drag to

Step 4: In order to be able to enter the selected content into the C3 and C4 cells, you need to set the appropriate formula and match the cell font color settings to the background color.
C3 formula

And, when G0 calls, "stack" is the following:

| Ari of F; t=1← —————— G1 Static link
| Ari of F; t=2← —————— g2 Static link
| Ari of F; t=3← —————— g3 static link
| Ari of F; t=4← —————— G4
. Assuming that the initial state is that all vertices in the graph have not been accessed, the depth-first traversal can proceed from a vertex v of the graph, access this vertex and then proceed from the unreachable adjacency Point of V to the depth first to traverse the graph until all the vertices in the diagram and V have paths are accessed; The above procedure is repeated until all vertices in the diagram are accessed, as an inaccessible vertex in the other diagram.
The process of depth-fir
