The Box–Muller transform, by George Edward Pelham Box and Mervin Edgar Muller, is a random number sampling method for generating pairs of independent, standard, normally distributed (zero expectation, unit variance) random numbers, given a source of uniformly distributed random numbers. The method . See moreSuppose U1 and U2 are independent samples chosen from the uniform distribution on the unit interval (0, 1). Let See moreThe polar method differs from the basic method in that it is a type of rejection sampling. It discards some generated random numbers, but can be faster than the basic method . See more

The Box–Muller transform is a pseudo-random number sampling method for generating pairs of independent, standard, normally distributed (zero expectation, unit variance) random numbers, given a source of uniformly distributed random numbers.
A Box Muller transform takes a continuous, two dimensional uniform distribution and transforms it to a normal distribution. It is widely used in statistical sampling, and is an easy to run, elegant way to come up with a standard normal model . There are many methods to generate Gaussian-distributed numbers from a regular RNG. The Box-Muller transform is commonly used. It correctly produces values with a normal distribution. The math is easy. You generate two (uniform) random numbers, and by applying an formula to them, you get two normally distributed random numbers.The Box Muller method is a brilliant trick to overcome this by producing two independent standard normals from two independent uniforms. It is based on the familiar trick for calculating. I = e−x2/2dx .
