In a random walk simulation, how do I get the mean and standard deviation of how many times the walk returns to the origin?

So I'm simulating a 1-dimensional random walk, with 1000 walks that each take 1000 steps. How do I calculate the average number of times that a walker returns to the origin and then the standard ...

Need software for generating self-avoiding random walks on a tetrahedral lattice

I am looking for FOSS code that can generate self-avoiding random walk trajectories on a tetrahedral lattice. The purpose of the exercise is to create random conformations of model polymer chains that ...
