1. Broadband router
Broadband routers play the role of shared gateways in the network, providing shared Internet services for computers in the network. At present, the market at home 4 Broadband router product prices are uneven, the general needs of the home network only need to buy a hundred or so products to meet, you can choose some of the market word-of-mo
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.

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

. 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

a variety of different graphics, in addition to running on open-source operating systems such as linux, it can also run on Windows platforms. Dia can make UML diagrams, flowcharts, and circuit diagrams, and convert them into multiple external formats (dxf, cgm, wpg, fig etc ). Has most of the functions of visio, at least need to draw uml and flowcharts and other tools available, and is not bad.

Developing the Seismic profile display program with Seismic. NET can save a lot of time. The following code shows how to use the least code to display a SEGY file.
= CgSegyReader (=. Controls. Add (plotControl );
Of course, professional profile display programs also require many interactive functions, such as scaling, dragging, following the mouse to display key information, reverse track order, setting the display mode, and displaying the cross cursor.
I recently wrote 15 subprograms,
different bit (bit) number--bit depth. The higher the number of digits, the clearer the color, the higher the contrast, and the greater the space occupied. The other determines the granularity of the bitmap, which is the number of points. A bitmap file is a collection of all the data that makes up its point, and its size is naturally equal to the number of points multiplied by the bit depth. The bitmap format is a huge family, including Common Jpeg/jpg, GIF, TIFF, PNG, BMP. The second scenario
