long gone are the times when I tried to hack something - spectrum+ 48k with interface 2, microdrive and romantic robot gadget, those were the happy times. I'll think I'll go one step further than that, people who designed the software for rice ...

hmm, this also looks interesting but I won't distract myself with it until I've fully solved the MM portion of the problem. After first reading this reminds me of the sunrise problem or the doomsday argument.

Fuzzy logic and probability are different ways of expressing uncertainty. While both fuzzy logic and probability theory can be used to represent subjective belief, fuzzy set theory uses the concept of fuzzy set membership (i.e., how much a variable ...

No, no rice cookers, French fries makers, pastry makers and especially, no microwave ovens for me. I really like to cook and am a firm believer that microwave is the antithesis of good cuisine. Only open flame, oven and sometimes pressure cooker ...

OK, after a dozen pages or so, here's something that everyone should understand, a really easy way to do constrained optimization in excel and get reports with lagrangians. First video, about excel solver and one easy example: ...

well, I had the same problem with excel 2007 and mt4, plus my broker (ibfx) recently added fifth decimal to bid and ask prices. The solution is very simple, you have to switch decimal and thousands separators in excel (comma and point symbols). You ...

The total derivative of the value function with respect to the parameter is the same as the partial derivative of the objective function evaluated at the optimal point.

The Lagrangian approach amounts to searching for points where the constraint is satisfied and the constraint and the level curve of the objective function are tangent to one another. With three variables, the Lagrangian conditions will say that the ...

We discussed multi variable functions a few months back. Here's an interesting book on the subject: Solved problems in Langrangian and Hamiltonian Mechanics by Claude Gignoux and Bernard Silvestre-Brac It will probably take me twenty readings before ...

Why don't you all just burn him at the stake? Would that make you happy? If anyone bothered to read (at least longer than last two pages ), he would realize that the unwritten book would be about reversals and that the discussion here is about money ...
