Random Seed Choice for LAMMPS Molecular Dynamics Simulations I want to create multiple molecular dynamics simulations using LAMMPS which are different only in the initial velocity of the atoms LAMMPS allows you to use a random seed to generate an initial velocity I plan to just use successive numbers, so if there are 5 simulations, the seeds would be
MCNP6: error -- bad trouble in imcn is usually . . . - Physics Forums Hello, I'm new to MCNP deck-building, and I'm trying to acquire an X-ray energy spectrum using MCNP6, on Windows 10 environment I'm running MCNP6 via MCNPX Visual Editor Version X_24E, and the deck is input using built-in "Input File" tab in MCNPX Visual Editor My input deck is given below
Will a Random Number Generator Eventually Repeat Its Numbers? I am just curious If I have a random number generator, eventually, if I wait long enough all possible numbers should began to repeat Or would the numbers not repeat? For example, if say the first hundred numbers were totally random 455688132547 etc would the machine eventually repeat
Standard Deviation as Function of Sample Size • Physics Forums If is a random variable with standard deviation then taking 100 samples of does not change the standard deviation of , but the random variable defined by the mean of 100 samples of has a smaller standard deviation than Neither of these standard deviations is the same as an estimator of a standard deviation
Probability that a Random String is a Word • Physics Forums Therefore the probability of a random string being a word is infinitesimal, about half of the probability that the random string is less than 5 characters To be precise, the number of strings of length 1 to 4 is 475254
