I don't know if I agree. The problem is an optimization task stated in the first post. How could later confirming that it is (or equivalent to) a search for Nash equilibrium (just terminology) be a disadvantage? I guess that it is possible in principle to regard both functions as function of...

Of course, its exactly what I want to do, calculate Nash Equilibrium for a case where each of the two agents controls a continuous function of multiple variables. Any idea of how these kinds of problems are solved?

I have an optimization problem and I am looking for a method rather than a solution here. I'll state it in a general form. Let there be two functions: f_1(x_1,\cdots, x_n,y_1,\cdots, y_n ) and f_2(x_1,\cdots x_n,y_1,\cdots, y_n ). Maximize f_1 with regards to variables x_1,\cdots, x_n with...

Amazing.. I was experimenting with a a method just like that one when I saw your reply. Interesting method that can be applied to any linear/nonlinear method. By the way since gauss-Newton linearizes the problem in each iteration I should get pretty decent results by making a weighted...

Allright, have read it through. Thanks One thing though, where does the errors from my original data come in?

Nothing I'm familiar with. Could you develop? Isn´t there any method equivalent to that using the covariance matrix in weighted linear least squares?

Uncertainty in parameters --> Gauss-Newton Hi guys! I have a set of datapoints, and i´m about to use Gauss-Newton to fit a model function (Lorentzian) to these points. So we´re talking abut a nonlinear least squares regression. How do I estimate error in function parameters given errors...

With the storage density of DNA, a 200 gram device ~ size of compact digital camera, can store about 1014 GB. That is A LOT more that the total amount of information on internet today. With the rate of advancements in biotech and computer science today.. such device should be possible to be...

..A project for this summer then!

Interesting!; If I get you right you suggest that since the more technology advances, the more specialized does professions has to be to handle the new technology, level of specialization could be a good measure of technological development. There is without a doubt a correlation, and with a...

Say that you want to create an index, to quantify technological level of humanity at any time. This index puts a value on the level of today as good as the level of technological advancement year 1662 or 400 BC. It can be used in predictions of the future and so on.. What factors; quantities...

I want the shift to be persistent.. till the next {faster than predetermined value}-movement. So for example with a slow twist I brighten up both groups of LEDs (relative brightness unaffected). With a quick twist the relative brightness is shifted to the corresponding group of LEDs. Now...

berkeman, If this was a school project I would probably have solved it myself. I made the post because this isn't really my field. I study physics at the University of Stockholm; and can probably say some t the electromagnetic foundation of this stuff; but electrical engineering, circuits and...

Thanks berkeman. Cant say I have much experiece at all. Know some basic electronics; but I am a quick learner! Had to search wikipedia a couple of times to understand your post.. Didn't think it had to be that complicated.. Sure it could be LEDs

A "selective" dimmer Hi! I need some help to solve a problem I can’t get my head around. I would be very grateful If someone could help me to get started. I need a circuit for a dimmer connected to two light sources. When the rate of change of the current is within a pre-determined value...
