Random number generators typically work on bits, so the range of numbers they can generate is a power of two. A range of characters like [0-9a-zA-Z] has 62 characters, which is two shy of a power of two (64), so the computer has to do some conversion between the ranges.That can...
To implement this approach, let's look at some methods to generate random numbers in Python: random.randint() and random.randrange(). We can additionally use random.choice() and supply an iterable - which results in a random element from that iterable being returned back. Using random.randint...
# Generate two random n by n matrices n = 10 a = matrix(runif(n*n,0,1),n,n) b = matrix(runif(n*n,0,1),n,n) # Multiply the matrix a by the transpose of b c = a %*% t(b) When the speed of linear algebra computations are an issue in R, it makes sense to use a ...
The rules of cellular automata were used to encrypt the secret text and generate random numbers. Each character of a secret text was treated as a cellular automaton and the rule 153 was used to encrypt it with the help of a secret key. The encrypted text was hide in the red plane of ...
A subsequent Python script loads the .mat file and ensures that numpy generates the same set of numbers for each seed. It outputs every seed for which Python and MATLAB differ. generate_matlab_randoms.m python_randoms.py On my mac, I opened a bash prompt and ran the two scripts as fol...
As a step toward a larger overhaul of math/rand (for example, #21835 or #26263), @robpike and I propose that math/rand seed the global generator randomly and deprecating Seed, rather than behaving as if Seed(1) had been called. A more ag...

to make sure that itcannothappen (maybe because a smaller number will crash your code), then simply generate your uniform random numbers in the range [0,0.1], test them, and reject any that are too small by replacing them with another uniform random number out of the same generator and ...
