Coupled simulated annealing (CSA) is a generalization of simulated annealing (SA), which is an optimization algorithm that doesn't use any information about the derivates of a function. The original paper describing CSA can be found here:
ftp://ftp.esat.kuleuven.be/sista/sdesouza/papers/CSA2009accepted.pdf
Essentially, CSA is like multiple simulated annealing (i.e. m
independent SA processes run in parallel), except that the acceptance
probability at each step is calculated as a function of the current
state across all m processes. For a more complete description of
the general CSA algorithm, see
Description of CSA.
Using pip:
pip install pycsa
