Description Usage Arguments Value Author(s) References Examples
This function implements a simulated annealing algorithm to optimize the posterior distribution of a normal mixture with two components and only the means unknown,
\code{like=function(mu){ -sum(log((.25*dnorm(da-mu[1])+.75*dnorm(da-mu[2]))))} }
with a schedule temp=1/log(1+t).

factor |
scale factor of temp that determines the scale of the random walk |
theta |
sequence of points explored by the simulated annealing algorithm |
like |
corresponding sequence of posterior values |
