Function Documentation

int parallel_tempering_decide_swap_nonrandom	(	mcmc **	chains,
		int	n_beta,
		int	n_swap,
		int	iter
	)

chooses one chain after another to swap. Swaps occur every n_swap.

References assert.

int parallel_tempering_decide_swap_now	(	mcmc **	chains,
		int	n_beta
	)

chooses one chain to swap by random. Swap occurs every time.

int parallel_tempering_decide_swap_random	(	mcmc **	chains,
		int	n_beta,
		int	n_swap
	)

chooses a chain to swap by random. Swaps occur with probability 1/n_swap

void tempering_interaction	(	mcmc **	chains,
		unsigned int	n_beta,
		unsigned long	iter
	)

does swapping chains and other mixes.

Parameters:

chains
iter	number of iterations that passed. Is a multiple of n_swap.
n_beta	size of chains
