The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Prisoner's Dilemma

Asked by DanRollins in Math & Science, Philosophy & Religion, Puzzles & Riddles

I have recently come across several references to this (Prisoner's Dilemma) and I'm finding it fascinating. Even my daughter mentioned it (by a differnet name) in regards to a college Sociology class -- she won a $10 prize by "doing the obvious" and defecting -- she couldn't understand why the other members of the class didn't come to the same conclusion!

If you don't know what I'm talking about, please see
Prisoner's dilemma (Wikipedia)
http://en.wikipedia.org/wiki/Prisoner%27s_Dilemma

The "iterated prisoner's dilemma" is the interesting variation.
It is discussed extensively in "The Selfish Gene" by Richard Dawkins. It shows how an equilibrium can be (often must be) reached -- "unselfish" cooperation ends up being the stable thing to do, even when every participant is only out for his own greed.

The "PD" also came up in an SF series I read by Kim Stanley Robinson ("Forty Signs of Rain," et. al). It applies PD to social contexts and uses the term "to defect" -- meaning to not cooperate -- in a way that is being seen more and more often in common vernacular.

It was also mentioned in an episode o the TV show "Numb3rs."

I thought it might be interesting to discuss this, partly because of the novely to being able to cross post in these three areas...

Philosophy and Religion -- cooperation is a key philosophical concept; evolution
Puzzle and Riddles -- PD is game theory
Math & Science -- Related scientific concepts such as "Nash Equilibrium" cellular automata, etc.

Some discussion points:
* Have you ever run across the idea of the PD in common media -- your
reading, TV shows, whatever?
* The idea's been around for a while: Did you study it in college?
* Name some practical uses for the "esoteric" game-theory concept
