In what sense is the triangle wave the best local realist approximation to the quantum singlet state correlation function?

Popular treatments of Bell's theorem always suggest that the triangle wave is *the* predicted correlation function according to local realism - as opposed to QM's cosine wave. In fact it is only...

Can someone suggest a better algorithm for computing the maximum likelihood estimator of a probability mass function with unknown labels?

We are presently using a combination of Metropolis-Hastings, EM, and stochastic approximation. but as the problem gets larger, it gets very very slow, and gets trapped at local maxima at the...
