Genetic algorithm is a kind of heuristic search, which belongs to evolutionary algorithm. It was originally designed according to Nature's natural choice of species and genetic laws. It simulates the natural selection, heredity and mutation of nature species, and improves the genes of a population.The genetic algorithm needs to set parameters such as crossover probability, mutation probability and iteration number, and the convergence of the algorithm

fittest.Replication (reproduction): When cells divide, the DNA of the genetic material is transferred to the newly produced cells by copying, and the new cells inherit the old cell's genes.Cross (crossover): DNA at one of two chromosomes is cut off, and the two strands are crossed together to form two new chromosomes. Also called gene recombination or hybridization;Mutation (mutation): Replication may (very small probability) produce certain replicat

Terminal devices in the work zone, such as telephones and fax machines, can be directly connected to each information outlet in the work zone by Corning FutureCom cat5e or cat5e twisted pair wires, or use adapters such as ISDN Terminal devices), balanced/non-balanced converter to convert and connect to the information outlet. 1-2.

pair is smaller than that of the aluminum foil of the same thickness ); The second is to resist the electromagnetic radiation interference between various pairs in the same twisted pair, and no cross skeleton is required. At the same time, the same line can transmit four confidential phone signals to the shielded twisted pair; there will be no electromagnetic interference (ANEXT) between the two adjacent twisted pair with the same color line ). Third, in terms of near-end crosstalk, quantitativ

when examining the channel performance of a negligible telephone line in the past. We recommend that you do not create a perfect cable bundle in cabling. Instead, you should use a random twist distance in the cables in the cabling group. This helps avoid overlong parallel cabling on different cables to reduce the impact of external crosstalk. During the evaluation, it is very important to examine the typical attenuation crosstalk ratio (ACR) of the cable category to be evaluated under different

. During this period, it went through four major application stages. First, from the middle of 1980s to the early 90 s, with the popularity of 10 Mbps Ethernet, three types of unshielded twisted pair wires have replaced various non-balanced cables (such as coarse and fine coaxial cables ). Then, from the early s to the mid s, with the vigorous promotion of Mbps Fast Ethernet, Category 5 unshielded twisted pair wires replaced Category 3 markets. Later, by the end of 1990s, with the full potential

The performance quality of an intelligent network integrated wiring system depends on factors such as reasonable design, produc

is, just read the data it finds, or write the data it needs to write.The simplest way to number a sector is to 1,2,3,4,5,6 sequential numbers. If the sectors are numbered sequentially around the track, then, during the process of processing a sector's data, the disk rotates too far, exceeding the interval of the sector (the interval is small), and the next sector that the controller reads out or writes to has passed through the head, perhaps a considerable distance. In this case, the disk contr

The macd is based on the sales signal by using the cross signal of the positive and negative deviation (± DIF) and the N-day average (n-day EMA, that is to say, we analyze the sales signal again with the crossover principle of fast and slow moving lines. In addition, macd indicators in the stock market software also has a secondary indicator-Bar = 2 × (DIF-DEA ), we can still use the

According to the individual coding method, the following algorithms can be used: real value recombination, discrete recombination, intermediate recombination, linear recombination, extended linear recombination.

" (Enhanced Cat 5, 5E). The U. S. TIA/EIA 568A-5 is 5E standard, "5E" is also known as "over 5 categories", which is the origin of 5E. Later, there were 6 categories, 6 categories, and even 7 categories, which are mainly related to the development of computer networks. According to Moore's Law, information requirements on computer networks are doubled every 18 months. Computer Networks are evolving to Gigabit Ethernet, the Application Requirements for the comprehensive cabling system are 4 pairs

High-bandwidth applications require the latest Network Cabling Technology. The cat6 cabling system meets today's commercial applications with its MHz bandwidth. According to the latest news, the TR42 Committee of TIA (Telecommunications Industry Associations) has passed the Six-class standard 568B-B.2.1, which will be officially promulgated by TIA on June 18.However, the technology is still improving. It is only a matter of time that the MHz bandwidth

The system is easy to expand and connect for easy maintenance and management. The architecture of the Integrated Wiring Scheme is described as follows. The subsystem of the building work zone consists of various work zones. According to the information point setting principle, each work zone is configured with single-hole and double-hole sockets. Each dual-hole

The more advanced copper cables are, the more sensitive they are to external exceptions. As the transmission rate increases, the installation and construction will affect the system performance ". Unreasonable pipeline design, nonstandard installation steps, and inadequate management systems wil

Cat6: the transmission frequency of this type of cable is 1 MHz ~ 250 MHz, cat6 cabling system at MHz integrated attenuation crosstalk ratio (PS-ACR) should have a large margin, it provides 2 times the bandwidth of cat5e. The transmission performance of cat6 cabling is much higher than that of cat5e, which is most suita
