List of Strengths and Weaknesses This list of strengths and weaknesses helps you to recognize those that apply to you. Know how to present these employee strengths and weaknesses in the best way when answering interview questions. Identify your top transferable competencies from your previous work and life experience and provide the right answer to the frequently asked interview question "What are your strengths?

Other problem-solving techniques Concisely stated, a genetic algorithm or GA for short is a programming technique that mimics biological evolution as a problem-solving strategy. Given a specific problem to solve, the input to the GA is a set of potential solutions to that problem, encoded in some fashion, and a metric called a fitness function that allows each candidate to be quantitatively evaluated.

These candidates may be solutions already known to work, with the aim of the GA being to improve them, but more often they are generated at random. The GA then evaluates each candidate according to the fitness function.

In a pool of randomly generated candidates, of course, most will not work at all, and these will be deleted. However, purely by chance, a few may hold promise - they may show activity, even if only weak and imperfect activity, toward solving the problem.

These promising candidates are kept and allowed to reproduce. Multiple copies are made of them, but the copies are not perfect; random changes are introduced during the copying process. These digital offspring then go on to the next generation, forming a new pool of candidate solutions, and are subjected to a second round of fitness evaluation.

Those candidate solutions which were worsened, or made no better, by the changes to their code are again deleted; but again, purely by chance, the random variations introduced into the population may have improved some individuals, making them into better, more complete or more efficient solutions to the problem at hand.

Again these winning individuals are selected and copied over into the next generation with random changes, and the process repeats.

The expectation is that the average fitness of the population will increase each round, and so by repeating this process for hundreds or thousands of rounds, very good solutions to the problem can be discovered. As astonishing and counterintuitive as it may seem to some, genetic algorithms have proven to be an enormously powerful and successful problem-solving strategy, dramatically demonstrating the power of evolutionary principles.

Genetic algorithms have been used in a wide variety of fields to evolve solutions to problems as difficult as or more difficult than those faced by human designers.

What You Need To Know

Moreover, the solutions they come up with are often more efficient, more elegant, or more complex than anything comparable a human engineer would produce. In some cases, genetic algorithms have come up with solutions that baffle the programmers who wrote the algorithms in the first place!

Methods of representation Before a genetic algorithm can be put to work on any problem, a method is needed to encode potential solutions to that problem in a form that a computer can process. One common approach is to encode solutions as binary strings: Another, similar approach is to encode solutions as arrays of integers or decimal numbers, with each position again representing some particular aspect of the solution.

This approach allows for greater precision and complexity than the comparatively restricted method of using binary numbers only and often "is intuitively closer to the problem space" Fleming and Purshousep.

This technique was used, for example, in the work of Steffen Schulze-Kremer, who wrote a genetic algorithm to predict the three-dimensional structure of a protein based on the sequence of amino acids that go into it Mitchellp. A protein is made up of a sequence of basic building blocks called amino acids, which are joined together like the links in a chain.

Once all the amino acids are linked, the protein folds up into a complex three-dimensional shape based on which amino acids attract each other and which ones repel each other.

The shape of a protein determines its function. Genetic algorithms for training neural networks often use this method of encoding also. A third approach is to represent individuals in a GA as strings of letters, where each letter again stands for a specific aspect of the solution.

The virtue of all three of these methods is that they make it easy to define operators that cause the random changes in the selected candidates: See the section on Methods of change for more detail about the genetic operators.

Another strategy, developed principally by John Koza of Stanford University and called genetic programming, represents programs as branching data structures called trees Koza et al.A. A1C A form of hemoglobin used to test blood sugars over a period of time.

ABCs of Behavior An easy method for remembering the order of behavioral components: Antecedent, Behavior, Consequence. SWOT is an acronym used to describe the particular Strengths, Weaknesses, Opportunities, and Threats that are strategic factors for a specific company.

There are different categories of weaknesses that you can choose from when answering interview questions about your weaknesses. However, do not choose a weakness at random. Instead, make sure the weakness you select is not critical to the job, and mention in your interview the ways you plan to improve upon this weakness. Systems Theory in Public Health - This paper delineates how analyzing the role of systems thinking in program planning, implementation, evaluation, and revision relates to: effective uses of information technology in public health practice, sources of inequality that produce health disparities across diverse populations, effective public health .

A SWOT should represent an organization’s core competencies while also identifying opportunities it cannot currently use to its advantage due to a gap in resources. As mentioned previously, the use of population-based indicators does have several strengths; however, it also has several weaknesses.
