. Population based search involves evolution of group of points in search space such as in ant colony optimization and evolutionary computation techniques. The mode of origin is another basis to distinguish between nature inspired and no nature inspired metaheuristic algorithm. Evolutionary computation and Ant Colony Optimization belongs to the class of nature inspired whereas tabu search and iterated local search belongs to the class of non nature inspired algorithms. Metaheuristic algorithms are also known as search based techniques or optimization algorithms which when applied to software engineering problems gave rise to Search Based Software Engineering (SBSE) [3] which reformulates software engineering problems as search problems. It is a collective attempt to shift from human based search to machine based search by applying search based optimization techniques. These methods encompass representation of problem and defining fitness function. SBSE treats search problem as one where optimal or near optimal solution are sought in a search space of solution by making use of fitness function that discriminates worse and better solution. Although many researchers, practitioners have applied search based optimization to software engineering domain, SBSE term was first coined by Harman and Jones [3] in 2001 in their work which advocates Search Based Optimization as a general approach to Software Engineering. A number of SBSE methods such as Simulated Annealing (SA), Genetic
Criminals have been committing crimes for centuries, and they are always fooling the police detectives and federal agencies sometimes. If the justice departments would actually look at the persons thought processes and reasoning before a crime is committed, the justice departments will be able to answer the reason for the crime. The different departments could possibly figure out why the criminal did what they did in the first. For instance, they should use a couple of criminology theories to help them with certain cases that are more difficult than the rest. The theories that the justice departments should use in their systems are the rational choice and biological theories of criminology.
The Making of the Fittest by Sean B. Carroll is a book that focuses DNA and how much we have learned from it. DNA has revealed so much when it comes to the evolution of different species and how they have adapted to forever changing environments.
Darwin’s Theory of Natural Selection, a scientific theory that supported the belief of evolution, was manipulated and applied to different areas of life, and thus it became the shaping force in European thought in the last half of the nineteenth century. Darwin, through observation of organisms, determined that a system of natural selection controlled the evolution of species. He found that the organisms that were most fit and assimilated to the environment would survive. They would also reproduce so that over time they would eventually dominate in numbers over the organisms with weaker characteristics. This new theory was radical and interesting to the scientific world but its effects reach far beyond this small institution of
In this essay I will be comparing and contrasting the Rational Choice Theory(s) and the Trait Theory(s). We will start with the history of the two theories and progress toward some of the individual principles in the theories. Next step will be explaining how each theory contributes to criminal behavior. My closing paragraph will conclude the essay as well as give detailed information on how society punishes the crimes committed.

Anthropologists are continuously exploring the far corners of the world in search of answers to how everything came to be and the process by which we as humans appeared on this planet. This is a difficult task and therefore, there are many branches of anthropology which strive to discern the pieces of the puzzle from different perspectives and approaches. Through the implementation of the scientific method, anthropologists have tested numerous hypotheses to create theories like the Theory of Evolution. First documented by Darwin, natural selection, the process by which a more fit individual survives and passes on their adaptive traits, has been discovered to play a crucial role in the evolution of
The GA [43] is basically an evolutionary algorithm developed by D. E. Goldberg in 1989, some of the other of its kind being evolution strategies, genetic programming, and EP. An evolutionary algorithm sustains a population of candidate solutions to an optimization problem. The population changes through repeated application of stochastic operators. GA considers the ELD problem as the environment where the living individuals are the feasible solutions. Finding globally acceptable solutions to the problem is analogous to adjusting to the surrounding by a natural habitat. Just as a new generation of a population is promoted by elimination of useless traits and by developing useful features, a new and better solution is found by iterative fine-tuning of fitness function. Generally, GA enters a loop with an initial population created with a set of individuals generated randomly. In each iteration (called “generation”), a fresh population is created applying a number of stochastic operators to the earlier
Industrialism is one of those of concept that has its good and bad contributions to this nation that people created and developed over time to survive. I believe if we are going to talk about industrialization, we need to connect the concept to Social Darwinism. In A People and A Nation, Norton and authors define Social Darwinism by Charles Darwin’s theory of “survival of the fittest” to the free-market system, arguing that competition would weed out weaker firms and allow stronger fitter firms to thrive” (466). If we look by human development, we can see that humans feed off of progress and to create survival following the wars and great depression. Especially in the technology game, technology of this time brought people telephones, electric
Around 70,000 years ago the first split in human skin occurred when a group of humans settled in Asia. Different situations favored for a lighter skin color. This is due in part to a lower level of sunlight. Now the simplistic guidance of natural selection can be seen in its true glory, as one type of human produced eumelanin in abundance to protect against the sun another group produced pheomelanin.
The process of evolution by natural selection begins with the overproduction of offspring, continues with the variation of these offspring, then the selection of the offspring that best fit the environment, and finally, the acclimatization of these offspring to their surroundings. While these steps don’t necessarily have a concrete duration of time in which they take place, the process follows this general pattern. Overproduction is necessary to be able to select from the most “suitable” or “fitting” offspring from a sizeable group. The three or so steps following overproduction coincide with one another and are necessary for the adaptation of offspring in an environment.
Evolution by artificial selection and natural selection have in common that they both favor certain traits over others. Moreover, they select on traits that are heritable, but they differ in the way traits are selected. Natural selection favors multiple ways to improve an individual’s fitness while in artificial selection, humans decide which traits they want to have in the next generation, which actually reduce the individual’s fitness.
One thing I found interesting was Darwin and his theory of evolution. Social Darwinism has been a big debacle for more than a century. It is significant and an important part of history because it challenged the way people thought about the orign of life and how humans came to be on Earth. Furthermore, Darwin's theory of evolution was controversy to the popular belief that God created humans as dominant creatures held in his likeness. He was the first to explain "natural Selection" and how humans evolved from apes. While Darwin still believed in God, he did not share the ideas expressed in the Bible. While Darwin's theory is still just a controversial topic among the world today due to the fact that the origin of Earth itself has not been decided
Throughout the Victorian Age, there was great controversy surrounding the relationship between religion and science. During this era, writers began investigating the idea of natural forces modifying organisms throughout their existence rather than God creating every organism with specific attributes to meet their needs. As a result, the ideology known as Darwinism emerged throughout the age. Later in the era, Darwinism was tweaked to describe the intricacies of human society and the varying levels of human economic and social classes. Social Darwinism was established in the second half of the 19th century based off of the Darwinist ideologies suggested by naturalists Robert Chambers, Charles Darwin, and Herbert Spencer. Social Darwinism applies
Exact optimisation method is the optimisation method that can guarantee to find all optimal solutions. In principle, the optimality of generated solution can be proofed mathematically. Therefore, exact optimisation is also termed as mathematical optimisation. However, exact optimisation approach is impractical usually. The effort of solving an optimisation problem by exact optimisation grows polynomially with the problem size. For example, to solve a problem by brute force approach, the execution time increases exponentially respect to the dimensions of the problem.
Diabetes is a systemic disease caused by a decrease in the secretion of insulin or reduced sensitivity or responsiveness to insulin by target tissue. (Beale, et al., 2011) The incidence of diabetes is growing rapidly in the United States and worldwide. An estimated 347 million people around the world are afflicted with diabetes. (Whalen, et al., 2012) According to World Health Organization (WHO), Diabetes prevalence among adults over 18 years of age has risen from 4.7% in 1980 to 8.5% in 2014. It is the major cause of blindness, kidney failure, heart attack, stroke and limbic amputation. World Health Organization (WHO) projects that diabetes will be the 7th leading cause of death in 2030. It is a complex and costly disease that can affect nearly every organ in the body and result in devastating consequences. The leading cause of non-traumatic lower extremity amputations, renal failure, and blindness in working-age adults, diabetes is also a major cause of premature mortality, stroke, cardiovascular disease, peripheral vascular disease, congenital malformations, perinatal mortality, and disability. (Cefalu, 2000) Insulin therapy and oral hypoglycemic agents have demonstrated improvement in glycaemic control. However, Insulin therapy has some disadvantages such as ineffectiveness following oral administration, short shelf life, of the need for constant refrigeration, and fatal hypoglycaemia, in the event of excess dosage.
