Genetic algorithm and its application in

Optimization problems[ edit ] Genetic Algorithm has been used extensively "as a powerful tool to solve various optimization problems such as integer nonlinear problems INLP " [3]. In a genetic algorithm, a population of candidate solutions called individuals, creatures, or phenotypes to an optimization problem is evolved toward better solutions. Each candidate solution has a set of properties its chromosomes or genotype which can be mutated and altered; traditionally, solutions are represented in binary as strings of 0s and 1s, but other encodings are also possible. In each generation, the fitness of every individual in the population is evaluated; the fitness is usually the value of the objective function in the optimization problem being solved.

Ivabradine reportedly improves heart rate variability in MVD-affected dogs with enlargement. They report finding that "the results revealed that chronic administration of ivabradine significantly decreased HR, BP, and RPP without adverse effects. All indices of time- and frequency- domain of HRV at M3 were significantly increased when compared with baseline values.

CoQ10 improves cardiac function in MVD-affected dogs in first canine study. They report finding that: In a September articlean international team of veterinary cardiologists led by Dr. Abbott compared the shapes of the mitral valves of 35 young healthy cavalier King Charles spaniels with those of 41 healthy dogs of other breeds mixed, Beagle, and border collieusing three-dimensional echocardiography RT-3DTTE.

Data from our laboratory show that the analysis of canine MV using RT—3DTTE is feasible and repeatable, and that healthy dogs have an elliptical, saddle-shaped MV, with parameters defining this shape similar to those described in healthy humans.

In contrast, dogs affected by MMVD have a more circular and flatter MV, therefore lacking some of the aforementioned favorable geometric characteristics. Based on the results of these studies, we analyzed the MV morphology of healthy CKCSs and compared it to the MV morphology of healthy dogs of other breeds.

They conclude by stating that a longitudinal study is needed to test their hypothesis. Our Cavalier Health Fund already has contributed thousands of dollars to this project and is raising additional funds for it.

We deem this research to be one of the most important ones for defeating MVD in our breed. The ultimate significance of this project would be to be able to predict the future severity of MVD in young CKCS breeding stock by examinging their mitral valves using this 3-D echo technology.

UK cardiologists find MVD-affected cavaliers are more likely to develop pulmonary hypertension than other breeds.

All dogs had enlarged hearts due to their MVD. Researchers devise a treatment plan for MVD-affected dogs in heart failure, based upon natriuretic peptide levels. Twenty-six dogs were in the study, which included five cavalier King Charles spaniels -- the largest number of any breed -- with four examinations over a 21 day period.

The dogs were divided into three groups, all three of which were in stable condition based upon routine treatments for CHF e. No dose adjustments were made to the current treatment. They concluded that the "application of a prespecified treatment escalation algorithm in dogs with recent history and treatment of 1st time CHF secondary to MMVD results in a decrease in plasma NTproBNP concentrations", and that "Use of this treatment escalation algorithm allows effective targeting of treatment for CHF in dogs against an objective criterion.

In sum, this study finds that weekly blood checks for levels of NT-proBNP can allow fine-tuning of the medications which manage MVD-dogs in heart failure. The study is interesting for a couple of reasons, but also seemingly impractical because of the frequency of blood tests required to measure the NT-proBNP levels.

It is interesting because it is another example of human studies being applied to dogs. There is much talk these days about "One Health", especially at PennVet school, which customarily means that what is learned by veterinarians in dogs and cats can be applied to humans.

Here is but another example of where the human medicine came first and then is applied to dogs. A couple of previous veterinary studies have pointed in that direction -- this May abstract and this September article.

The impracticality of this frequency of periodic testing is obvious. Considering that some MVD-afffected dogs in Stage C CHF have been known to survive for a matter of years, this could amount to a very time-consuming and expensive protocol.

They primarily were testing the cough-suppression efficacy of alacepril over a period of four weeks. They report finding that alacepril resolved or lessened the cough in 20 The drug was safe and well tolerated.

Alacepril treatment resolved or improved cough in 20 dogs Different conditions of cardiac loading may influence the effectiveness of alacepril. Long-term clinical trials should be performed to determine the benefits of alacepril based on the onset of CHF, duration until treatment failure, and survival time.

Scollanthey tested cardiologists, radiologists, and interns, to evaluate the accuracy of subjective x-ray determinations of left atrial enlargement LAE compared to echographic left atrium LA size assessments.

The subjective x-ray criteria included what are called "Roentgen signs" named after the discoverer of the x-ray.The Simple Genetic Algorithm (SGA) is a classical form of genetic search.

Viewing the SGA as a mathematical object, Michael D. Vose provides an introduction to what is known (i.e., proven) about the theory of the SGA.

What Genetic Genealogy Is Snapshot Genetic Genealogy. Genetic Genealogy (GG) is the combination of genetic analysis with traditional historical and genealogical research to study family history.

For forensic investigations, it can be used to identify remains by tying the DNA to a family with a missing person or to point to the likely identity of a perpetrator. Level-2 Genetic algorithm: A level-2Soft computing, such as genetic algorithm, can be used to optimise the design of rectifier systems [11], [18] or to adapt the parameters of advanced controls such as active rutadeltambor.comularly introduces a new active damping method that does not need the use of more sensors and that can be tuned using genetic algorithms.

The earliest instances of what might today be called genetic algorithms appeared in the late s and early s, programmed on computers by evolutionary biologists who were explicitly seeking to model aspects of natural evolution.

Genetic programming is a method for getting a computer to solve a problem by telling it what needs to be done instead of how to do it.

Koza, Bennett, Andre, and Keane present genetically evolved solutions to dozens of problems of design, optimal control, classification, system identification, function learning, and computational molecular biology. "Through this program, ATHN and its affiliated treatment centers were able to offer patients free genotyping, which has been a great benefit to both providers and patients.
