Procoli extracts profile likelihoods in cosmology. It wraps MontePython (
ascl:1805.027), the fast sampler written specifically for CLASS (
ascl:1106.020). All likelihoods available for use with MontePython are hence immediately available for use. Procoli is based on a simulated-annealing optimizer to find the global maximum likelihoods value as well as the maximum likelihood points along the profile of any use input parameter.
