that the local optimal solution is the global optimal solution, which is the simplex algorithm idea.Algorithm process:Pivot operation: Select a base variable and a non-base variable to swap itSimplex operation: The main process, starting from a basic solution, through a series of rotating shaft operation, to find the optimal solutionExample:Solve the following problems:First step: Interchange X1 and X6Step two: Interchange X3 and X5The third step: In

The simple algorithm is the classical method to solve the linear programming, it is proposed in the 50 's, its basic idea is to traverse all vertices along the edge in the feasible domain, find out the optimal value, that is the optimal value of the algorithm. The algorithm is executed as follows: To find the initial base vector to construct the simplex table in the corresponding C of all the non-base vectors, find a minimum CI, if the CI is greater t

What are the advantages of a small pluggable (SFP) port for a Gigabit Ethernet switch? How do I connect the four SFP ports of a d-link DGS 1248 t smart switch? I think the main advantage of the SFP port is the flexibility to connect to the network. The SFP port is a hot-swappable input/output device that can be plugg

The SFP is the abbreviation for the small FORM pluggable and can be easily understood as an upgraded version of the Gbic. The SFP module is half the size of the Gbic module, and can be configured with more than one port number on the same panel. The other features of the SFP module are basic and gbic consistent. Some switch vendors call the

These days, when HP acquired H3C, it was rare to see 3COM with 3 O-markers. But the problem, a year ago a project bought a 3COM switch 2924-SFP plus switch (PS: pure switch, no readable data). At that time saw a default management IP in the back, so log in to the Web interface configuration can be. Later the project bought H3C S5500 switch, do not have this switch, so idle.Due to the recent equipment is more tense, need to enable, the problem came, bu

How to disable the SFP module on H3C vswitches and other devices? The following warning is displayed: OPTMOD/4/PHONY_MODULE: GigabitEthernet1/0/2: This transceiver is NOT sold by H3C. h3C therefore shall NOT guarantee the normal function of the device or assume the maintenance responsibility thereof! This is a warning when SFP module is used on H3C vswitches, routers, and other devices. It generally means t

1. The concept of linear programmingLinear programming is to study the extremum problem that makes a linear objective function take maximum (or minimum) under a set of linear inequalities or equality constraints .2. Standard form of linear programmingfeatures : The objective function is great , the equality constraint , and the variable is non-negative .MakeThe matrix expression of the linear programming standard form is:Conventions:How to make a standard shape:(I) The objective function is grea

slope of-1. Z as a variable, let the feasible area in the coordinate system move to obtain the maximum value of z, such as:Get.While it is not easy to graphically represent a linear plan with more than two variables, the same intuition is still true. As in two-dimensional space, because the feasible area is convex (why?) ), the point set that obtains the optimal target value must contain a vertex of the feasible region. Similarly, if there are n variables, each constraint defines a half space i

The network card transmits the data, according to the direction of the data flow can divide into four kinds of basic transmission way: full duplex, Half-duplex, simplex and automatic detection four kinds of way. But simplex is now rarely used, and the following are just two common ways If at any point in the communication process, the information can only be transmitted by one Party A to the other party B

Linear programming (Linear PROGRAMMING,LP) is one of the most classical algorithms, and the most common method to solve this problem is simplex method. This blog is dedicated to explaining the process of simplex algorithm and explaining it in detail in the simplest and most detailed language.In the middle school curriculum, we are all simply in touch with linear programming, at that time, we usually analyze
