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.

Courses The mission of the Stanford Graduate School of Business is to create ideas that deepen and advance the understanding of management, and with these ideas, develop innovative, principled, and insightful leaders who change the world. The two-year Master of Business Administration M. Interdisciplinary themes of critical analytical thinking, creativity and innovation, and personal leadership development differentiate the Stanford M.

Dual Degree programs are offered with the School of Medicine M.

It is an opportunity for us to reflect on the language and ideas that represented each year. So, take a stroll down memory lane to remember all of our past Word of the Year selections. Change It wasn"t trendy , funny, nor was it coined on Twitter , but we thought change told a real story about how our users defined Unlike in , change was no longer a campaign slogan.

But, the term still held a lot of weight. Here"s an excerpt from our Word of the Year announcement in The national debate can arguably be summarized by the question: In the past two years, has there been enough change?

In this context of changing and challenging market requirements, Gas Insulated Substation GIS has found a broad range of applications in power systems for more than two decades because of its high reliability, easy maintenance and small ground space requirement etc. SF6 has been of considerable technological interest as an insulation medium in GIS because of its superior insulating properties, high dielectric strength at relatively low pressure and its thermal and chemical stability.

SF6 is generally found to be very sensitive to field perturbations such as those caused by conductor surface imperfections and by conducting particle contaminants. The presence of contamination can therefore be a problem with gas insulated substations operating at high fields.

To register, a student must obtain permission from the faculty member who is willing to supervise the research.

I thought I"d try to synthesize what I took away from the posts and how my own thinking has developed. First up, I think it"s gratifying to see that the the basic premise: There was a time in the not-so-distant past that I wouldn"t be able to even establish this baseline in conversations that I"d have. The argument therefore has moved to one of tradeoffs: Here are some of the main arguments that have come up: Author identity carries valuable signal to evaluate the work.

This argument manifested itself in comments and I"ve heard it made in the past. One specific version of it that James Lee articulate s is that all reviewing happens in a resource-limited setting the resource here being time and so signals like author identity, while not necessary to evaluate the correctness of a proof, provide a prior that can help focus one"s attention.

My instinctive reaction to this is"you"ve just defined bias". But on reflection I think James and others people who"ve said this are pointing out that abandoning author identity is not for free. I think that"s a fair point to make. But I"d be hard pressed to see why this increase in effort negates the fairness benefits from double blind review and I"m in general a little uncomfortable with this purely utilitarian calculus when it comes to bias.
