If you are going to optimize your own objective function with De, try the following settings for the input file first: choose method e.g. de/Rand/1/exp, set the number of parents np to 10 times the number of parameters, Select Weighting Factor f = 0.8 and crossover constant Cr = 0.9. make sure that you initialize your parameter vectors by exploiting their full numerical range, I
This section describes the issues that should be avoided when creating a clean UML diagram. I believe you will be familiar with the methods for creating a clean UML diagram through this article, let's take a look at how to draw a clean UML diagram.

The user can set up the network topology directly using the towing method in the software's graphical user interface, and can provide the detailed processing process of the data packet traveling in the network, observe the network

The area that each chromosome occupies on the roulette wheel is expressed in proportion to the degree of fitness score.Based on the values in, we create the following "roulette".Now, the roulette wheel starts to spin, and we will be selected as the first parent by the area that the fi

LAN to share a public network IP address surfing the Internet, and to achieve the corresponding function. second, make switch with Broadband routers (including wireless routers) are generally built with a four-port switch, so you can directly make it a real switch to use. Perhaps a lot of readers will ask, is not there a uplink on the switch? And the four-port switch built into the broadband router is not. In fact, the role of the uplink port is to solve the network equipment interconnectio

The port of the core switch is mainly a fiber type, but the price of the switch fibre port is very expensive and requires special attention from the user, while the fibre port of the switch is not stacked and can only be used for cascading purposes. Analysis of the switch fiber port Cascade connection mode and basic types, welcome to add message.
Cascading can use either a normal port or a special mdi-ii port. A pass-through cable should be used when the two ports that are cascaded are normal (
the same location is expensive, and often leads to network internal blocking. In the future, in order to better support VoIP, IPTV and other real-time IP services, also requires data network to improve business quality.
Considering that the same I/O port core routers have a market price of 5 times times the SDH device, it is recommended to use a light crossover machine to transfer IP direct service to improve efficiency, while IP routers focus on 3-
local optimal solution can jump out of probability and finally tend to the global optimal.
The key of the simulated annealing algorithm is to control the temperature (probability) to reduce the speed of the parameter R, this parameter range is 0
The simulated annealing algorithm can not guarantee the real optimal solution, but the optimal solution with high quality is obtained under the condition of good efficiency.

2. Randomly select 2 nodes to reverse the node order between the 2 nodes in the path.
3. Randomly select 3 nodes m,n,k, and then shift the node m and n between nodes to node K.
"Algorithm Evaluation"
Simulated annealing algorithm is a kind of stochastic algorithm, and it is not always possible to find the global optimal solution, and it can find the approximate optimal solution of the problem fairly quickly. If the parameters are set properly, the simulated annealing algorit
protocols such as PPTP (Point-to-Point Tunneling Protocol). Once the routing lookup is complete, the packet must be sent to its output port with a switching switch. If the router is an input-side plus queue, there are several inputs that share the same switch. The final function of this input port is to participate in the arbitration agreement for public resources such as switching switches.
Switching switches can be implemented using a variety of different techniques. The switch technology th

need to transfer data through a hub or vswitch. However, when connecting two NICs, you cannot directly use the express Connect line, but you must use the cross-type network line. When creating a cross-type network line, you must use the T568A line sequence to connect one end to the other, the other end uses the T568B line sequence connection. If the crossover network cable is not created in accordance with such standards, even if the two computers ca

In addition, according to the different network devices connected to the two ends of the network cable, the network cable can be divided into two types: Direct Line (parallel line) and cross line. A straight-through line (parallel line) is a network line created according to the 568a or 568b standards described earlier. On the other hand, the line sequence of the crossover
