I am trying to generate random points on the surface of the sphere using numpy. I have reviewed the post that explains uniform distribution here. However, need ideas on how to generate the points o...

Given some interval [a, b] of indices (64-bit unsigned integers), I would like to quickly obtain an array that contains all of these indices ordered according to a uniformly distributed hash functi...

I want to get a 2-D torch.Tensor with size [a,b] filled with values from a uniform distribution (in range [r1,r2]) in PyTorch.

I am looking to be able to generate a random uniform sample of particle locations that fall within a spherical volume. The image below (courtesy of http://nojhan.free.fr/metah/) shows what I am lo...

Imagine 10 cars randomly, uniformly distributed on a round track of length 1. If the positions are represented by a C double in the range [0,1> then they can be sorted and the gaps between the c...

Is p = rand(-1.:eps():1., 100000) a good way to get random Float values in [-1, 1]? A common suggestion seems to be 2. * rand(100000) - 1. instead, but this doesn't ever return 1 since rand's ran...

I could not find a built-in function in Python to generate a log uniform distribution given a min and max value (the R equivalent is here), something like: loguni[n, exp(min), exp(max), base] that ...

In the documentation it is said that there is a chance that uniform(0,1) can generate the values 0 and 1. I have run uniform(0, 1) 10000 times, but it never produced zero. Even in the case of uni...

In this link, it says that truncated MD5 is uniformly distributed. I wanted to check it using PySpark and I created 1,000,000 UUIDs in Python first as shown below. Then truncated the first three ch...

I want generate a number in Gaussian and Uniform distributions in matlab. I know this function randi and rand() but all of them are in normal (Gaussian) distribution. How can a generate a random nu...

I wanted to generate a random real (I guess rational) number. To do this I wanted to use runif(1, min = m, max = M) and my thoughts were to set m; M (absolute) as large as possible in order to ma...

I want to sample a two-dimensional vector x from a uniform distribution with ∥x∥ ≤ 1. I know I can sample from a uniform distribution as numpy.random.uniform(0.0, 1.0, 2) but how can I make sure...

Assume it's given a set of rectangles with different areas and some rectangles could overlap. Objective is generating of a uniform random point among rectangles' areas. Rectangle is defined as a p...

The algorithm in this question tells us how to efficiently sample from a multidimensional ball. Is there a way to similarly efficiently sample from a multidimensional ring , i.e. have r1<r<r2...

[I'm splitting a population number into different matrices and want to test my code using random numbers for now.] Quick question guys and thanks for your help in advance - If I use; 100*rand(9...

std::uniform_int_distribution accepts any of <random>'s PRNG's, including the ones that are consistent across implementations and platforms. However, std::uniform_int_distribution itself does n...

I use the C++ random number utility library in quite a few places. It might not be perfectly comfortable (e.g. no base class for an arbitrary distribution), but - I've learned to live with it. Now...

Let me start by stating what I'm trying to accomplish: I need to randomly generate a set of numbers within a range I would like those numbers to be somewhat uniformly distributed I need to be abl...

I have two options of code: Option 1 int myFunc() { return new Random().nextInt(); } Or: Option 2 private static final Random random = new Random(); int myFunc() { return random.nextInt();...

I'm trying to convert this line of matlab in C++: rp = randperm(p); Following the randperm documentation: randperm uses the same random number generator as rand And in rand page: rand ret...

If I were to produce floating point values in the following way: template <typename T> T RandomFromRange(T low, T high){ std::random_device random_device; std::mt19937 engine{random_devic...
