Each individual represents a variable or a part of the problem which is needed to be optimized. In this paper, the locations of cracks (my blog) and their depth are needed to be optimized by the GA. So these individuals represent the number and location of crack and the corresponding crack depth. For the present method, each control gene is encoded into a binary bit and the activation of the parametric gene is governed by the value of the first-level control genes. While the parametric part represents the depth of crack. Therefore, the standard methods of mutation and crossover may apply independently to each level of genes or even for the whole chromosome if this homogenous. However, the genetic operations that affect the high-level genes can result in changes within the active genes which eventually lead to a change in the lower level genes. By using this encoding technique, the total number of candidate crack elements is significantly reduced. Thus that the genetic operators can be applied only in the ‘active’ elements (damaged) leaving the ‘inactive’ ones (undamaged) unchanged. This is the precise reason why the HGA is not only able to obtain a good set of system parameters, but can also determine a minimized system topology for the crack detection. In this paper, we introduce for each spring element a binary variable which can assume either an ‘active’ or ‘inactive’ state, while each normalized crack depth was denoted as a 10-bit binary number.

Genetic algorithm through genetic operators (crossover and mutation) restructures individual in the population; by selecting operation, it constantly optimizes the individual structure and searches the optimal structure of the individual and, finally, achieves the goal of becoming closer to problem of the optimal solution. It can be seen that the genetic algorithm is the process of alternating work in the coding space and solution space and its genetic operation on chromosome in the coding, and it evaluates and chooses the solution in the solution space. The bridge between them is the encoding and decoding. Code is converting the solution of the problem space to variable chromosome of genetic space. On the contrary, the decoding is the operation where the chromosome coding is mapped in the problem space. The relationship between them is shown in Figure 2.

Genetic algorithms mimic biology in that the individuals with the best fitness cores are most likely to breed and pass on their genes. But we do not simply take all the best individuals from our population to breed, as this might risk ‘in-breeding’. Rather, we use a method that means better individuals are moire likely to breed, but low fitness individuals at times may be chosen to breed.

With the rapid development of Internet technology and information technology, digital communication is more and broader: people can release on the Internet all kinds of information anytime and anywhere. Digital image is the most intuitive, visual, and abundant information carrier, due to its convenience, speed, lack of geographical restrictions, low cost, high efficiency, and so forth; it has been more widely used and has become one of the main information network era expressions. However, people enjoy all sorts of convenience brought about by the digital image but also face some difficult security problems, such as personal privacy protection, business and military information protection, and electronic products illegal copying and dissemination. So how to protect digital image in the transmission process has become the focus of the industry.

Genetic algorithm is different from traditional search algorithm; it first randomly generates a set of initial solutions, namely, “population,” where each individual in population, namely, a solution vector, which is called “chromosomes,” begins the search process. These chromosomes evolve in the subsequent iterations and generate the next generation of chromosomes, called “offspring”.

It is assumed in this study that the FE analysis is accurate and any deviations from reality are random noise and not systematic modeling error. For applications to real structures some methods such as finite element model updating can be used to match the modal predictions of the undamaged structure with experimental data. Now the following discussion will be directed to the test using noise contaminated simulated data. The additive noise for the natural frequencies simulating the uncertainty present in experimental measurements and the modeling process is considered here. Table 4 shows the results for four different noise levels: Noise-free, 0/15 %, 0/2 % and 0/3 % noises.

Conformal antennas were developed in the 1980s in order to be integrated with the outer metallic layers of aircrafts, with the purpose of reducing the aerodynamic drag and improving aircraft speed, fuel consumption, and gas emissions. Conformal antennas gradually replaced conventional ones that project from the aircrafts’ hull. As long as commercial applications are considered (including shipping), the technical limitations and constraints are similar to avionics, but the application of conformal antennas was until recently limited due to the high related costs of etching and integration.

I can't split up an instruction, therefore I need the crossover points to lie on 4, 8. I'm sure you can figure out a more elegant design yourself. This study aims at proposing a medical image encryption method based on a hybrid model of the Modified Genetic Algorithm (MGA) and coupled map lattices. Since our network consists of 3 layers (input, hidden, and output) with 2 neurons. And crack characteristics of engineering structures are mainly determined by established based on quantum genetic algorithm, then MATLAB programming is. In each generation, better approximations of the final solution are obtained by means of a selection process commensurate with the value of the answers and the reproduction of the selected answers with the help of operators that mimic natural genetics.

Gram schmidth Algorithm 1.0 - SADAF KHANTools / Development Tools
On top of the high related costs of integration, conformal antennas also suffer from severe constraints imposed on their design that arise due to the predefined and often counterproductive shape of the flat area that they need to conform with. This affects the performance of the antenna array, its shape, the elements spacing, the relative signal phase, and so forth. Thereupon, it is necessary to investigate counterintuitive and arbitrary antenna shapes in order to compensate for these constraints.
The algorithm repeatedly modifies a population of individual solutions
Various runs of the proposed GA optimization platform have been executed with the purpose of designing a patch antenna of arbitrary shape suitable for applications around 1/5 GHz, like a GPS receiver. The substrate of the patch antenna should be of the FR4 type, with a substrate thickness of 1/6 mm and a dielectric constant equal to. Furthermore, the patch antenna should be fed via standardized SMA cables and connectors that are also integrated in the simulation, design, and optimization of the patch.
Using arbitrary-shape antennas may be a significant aid in developing high-performance antennas and arrays under strict constraints. Conformal antennas are a priori considered as a type of antennas that need to comply with such strict constraints and at the same time are of high importance for avionics and marine communications. With the proposed platform we were able to design a GPS antenna of low profile and high performance. Future work will include the design of planar antennas that will be etched at the outer metallic layers of ships and aircrafts using our design platform.
Let’s test our function with a high mutation rate (0/25) to see the effects. You can change the mutation rate and see what happens (a mutation rate of 1/0 will invert all genes).

Violations are calculated by iterating through every queen and checking horizontally, vertically, and diagonally for other queens. Each violation is totalled up, and at the end they are divided by 2 since violations were overcounted. This could certainly be optimized further.
It implements steepest descent Algorithm with optimum step size computation at each step
In this paper, a hierarchical genetic algorithm (http://zbsmarket.ru/free/?key=628) is used to detect multiple cracks in a beam. An integer “1” or “0” is assigned for each control gene which can denote either a damaged or undamaged state. The associated parameter genes representing the normalized depth of crack are activated in the lower level structure. The hierarchical genetic algorithm is more attractive not only because it can avoid premature convergence but also it significantly reduces the total number of finite element analyses in comparison with its predecessor (simple GA). It is concluded in this study that it may be probable to use the described procedure to characterize multiple cracked (helpful resources) elements in terms of identifying their numbers, locations, and the level of depth. Numerical results for various damage cases demonstrate that the effectiveness of the present technique. The technique is also attractive from the practical point of view, because we consider only natural frequencies in the objective function.
Cuckoo Optimization Algorithm 1.0 - Ramin RajabiounTools / Development Tools
Conformal antennas and antenna arrays (arrays) inherit their name from the fact that they “conform” to the shape of a 2D yet not planar surface. More specifically, conformal antennas are flat curving antennas that follow or are embedded to an object of predefined shape, like that of an aircraft’s nose. Conformal antennas and antenna arrays (arrays) have become necessary for vehicular communications (where a high degree of aerodynamic drag reduction is needed) due to their so-called “conformity” to arbitrary surface shape, like in avionics and high-performance ships or submarines.

Model Determination using Genetic - Housam BinousTools / Development Tools
Image replacement and diffusion both change the relevance of the original image, making the information entropy change. And image diffusion is based on image correlation transformation among adjacent pixels according to certain rules, but it may cause some image information loss. Transform domain image encryption is mainly through some sort of orthogonal transformation on the image; then, it is encrypted when it is coding processing. Like image encryption based on tree structure and image encryption based on SCAN language , these image encryption schemes involve the problem of how to generate pseudorandom sequences; now the problem has no good solution. By using neural network with the parallel distributed processing, highly nonlinear association memory , and other characteristics, to encrypt the image information, we call it artificial neural network image encryption. But the neural network needs a lot of neurons data to encrypt, because it cannot be adaptive to generate neural networks, then increases complexity of encryption, and reduces efficiency of encryption.
