Show me.
P.S. My brain refuses to solve such a strange, alien problem. The monotonicity of the first derivative is not satisfied. And this prevents me from solving the equation on x by secants/Newton's method, easily and simply. Although a dumb search (strongly optimized) solves it, and rather quickly.
If it wasn't a double-decker, but just multiplication, everything would be easier and clearer.
Here, it's the dumbest algorithm. It's quick, though. It needs about 50 iterations to get an accuracy of 10^(-8).
Here is avtomat's picture from the previous page, for starters.
And now mine (same parameters):
And code:
P.S. It is good to remember that this algorithm only works for this function. It is monotone, and therefore has a single root. Unfortunately the non-monotonicity of the first derivative makes it impossible to apply the tangent method. True, the loss is not felt at all: the computation time taken with GetTickCount() is not even counted.
help me decide. The club asked...
.black triangle - black move...white triangle - white move....equals draw....plus wins...minus-loses...
the number of moves is unlimited...
Nos 27 and 28 - solved.
