BIRD SWARM ALGORITHM: BSA is a new meta-heuristic swarm intelligence algorithm proposed by Xian-Bing Meng [35] , inspired by social behavior and interaction of birds. Different birds gather food in different ways. Foraging is the searching for food resources or gathering food either for immediate consumption or future storage. Birds forage in flocks because they gather more information in flocks than their own intelligence. Group foraging boost-up the chances of detecting predators. While…

Describe how the quicksort works including a discussion of the pivot, how it is selected, and why the pivot is important to the quicksort. Let’s start describing what pivot is, its function and why is so important. The pivot is the element that basically divides the array in two halves, where the left half contains the smaller values and the right half contains the greater values. The pivot can be selected in many ways. First, last, middle element, actually any element of the array can be…

ABSTRACT: Genetic Algorithm is one of the global optimization schemes that have gained popularity as a means to attain water resources optimization. It is an optimization technique, based on the principle of natural selection, derived from the theory of evolution, is used for solving optimization problems. In the present study Genetic Algorithm (GA) has been used to develop a policy for optimizing the release of water for the purpose of irrigation. The study area is Sukhi Reservoir project in…

In “Machine Bias” and “Secret Algorithms Threaten the Rule of Law”, many issues arise with the application of algorithmic tools that use predictive measures to establish scores for individuals that determine the likelihood that they will commit a crime. These crime predicting scores are being used in a utilitarian way that makes sure people with high (more likely to commit crime) scores are incarcerated and kept away from the public while lower (less likely) scored people aren’t punished as…

ANT COLONY OTIMIZATION basics and algorithm 3.1. ACO algorithm introduction and basics The concept of ACO has been inspired by observation of real ants while wondering for food source. An ant while in search of food source lays a certain amount of pheromone trail along the path traversed. The laying of pheromone serves dual purpose to the ant. Firstly, it marks the path for other randomly moving aunts and secondly, it helps the aunt to return to its original source. Now, whenever a redundantly…

In this way file is reconstructed back from its shares. The size of each piece is |F| / (n-k), where |F| is size of secret/data, which is smaller than size of each piece produced through algorithm explained in [52]. In this scheme, m-1 shares of file F may provide some information about F. So in this scheme it is advisable to encrypt F before dispersing it and decode it after reconstruction of the encrypted version. One possible attack on the security of the data dispersed among servers would be…

without needing for the posting list intersection protocol. Our scheme consists of six algorithms KeyGenerator, BuildIndex, DocEncrypt, Trap- doorGen, SearchIndex and DocDecrypt which are scattered between two phases, Sender Phase and Retrieval Phase. 3.2.3.1 Sender phase This phase includes three algorithms as detailed below: I. Key generator: the data owner DO initiates the scheme by using KeyGenerator(µ)…

is on the symmetric encryption. There are some basic information about this type of cryptography will be reviewed. Then, symmetric cryptography advantages and problems will be covered. After that, comparison on several symmetric algorithms are discussed. These algorithms are DES, Triple DES, AES, RC2, RC4, RC6, and Blowfish. Keywords—Cryptography, Symmetric Encryption, Encryption, Decryption, DES, Triple DES, AES, RC2, RC4, RC6, Blowfish. I. INTRODUCTION Cryptography is an enormous topic, for…

I read the book Nine Algorithms that Changed the Future by John MacCormick. Nine Algorithms that Changed the Future is a 210-page book that covers fascinating algorithms that we all use in our everyday lives. As MacCormick puts it “Every day, we use our computers to perform remarkable feats. Uploading a photo to Facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact.” MacCormick’s writings explains…

Colony Algorithm. The proposed algorithm is the implementation of ABC algorithm with the key concept of GA technique.The GABC is actually the hybrid approach of Artificial Bee Colony Algorithm and the Genetic Algorithm.In this method we extend Genetic Algorithm with Artificial Bee Colony operators i:e Employed Bees and Onlooker Bees to improve the solution space named as Genetic Artificial Bee Colony Algorithm (GABCA). Genetic algorithms belong to the larger class of evolutionary algorithms…
