This is just speculation, but perhaps what VLC is attempting is to simulate... perfect randomness. That is, each song is picked uniformly at random, independently of previous songs. According to the coupon collector problem, if you have $n$ songs in your list and want to hear all of them, you will have to wait for roughly $n\ln n$ songs to be played. By that ...

Question a): Here is the output from python console. >>> import math >>> math.log(3,10) * (3**(3**3)) 3638334640024.0996 >>> math.pow(10, 0.0996) 1.2577664324512539 The first 5 most significant digits are almost the same of that of Wolfram, 12577 vs 12580. If we try the following at my favorite online arbitrary precision ...

Note: For this answer I chose to assume that the question was somewhat naive, since, as remarked by @D.W. in his comment, the OP should otherwise search for himself in wikipedia and other places on the web, and the spectrum of problems and techniques is far too wide for an answer here. So I am focussing on the fundamental aspects, obvious to a seasoned ...

I don't know of a full blown library, but based on [1] there is a really fast practical C++ implementation available from the author's homepage here. [1] Valmari, Antti. "Fast brief practical DFA minimization." Information Processing Letters 112.6 (2012): 213-217.

If you found Structure and Interpretation of Computer Programs interesting, you might like Functional Differential Geometry (It's from the same authors) . Differential geometry is deceptively simple. It is surprisingly easy to get the right answer with unclear and informal symbol manipulation. To address this problem we use computer programs to communicate ...

A similar question has been asked before, that may answer your question, here. Quoting the answer: This is basically an instance of the line segment intersection problem. One standard approach is to use a sweep line algorithm. For instance, the Bentley-Ottman algorithm would be a reasonable choice, and is not too difficult to implement. At each iteration ...

I have a library of over two thousand songs and I've always noticed VLC's flawed shuffling system. It will play the same song every few songs, or it will prioritize songs from randomly picked folders. Recreating this phenomenon as I write this proves exactly that: With shuffle already selected I press open folder and select my music folder and a song from '...

Compute 4^4^4 and you will know how much pairs of bits 4^4^4^4 will require to represent.

$1.0531229 \times 10^{65}$ is approximately $2^{216}$ so when you say " every possible $216$ digit number " I assume you mean every possible sequence of $216$ binary digits i.e. bits. Each sequence occupies $216$ bits, so the minimum storage for all possible sequences (if we ignore factors like aligining on word boundaries) is \$216 \times 1.0531229 \times ...

I have just found this correct answer on the web (by someone else): A helix is a circle that moves up with time. Hence, the equations for one helix are: x(t) = sin t y(t) = cos t z(t) = t A double helix include two helices that are offset by half a turn. So, the equations for the second helix would then be : x(t) = sin t y(t) = cos t z(t) = t + \pi
