Overview: This paper proposes a probabilistic approach for estimating parameters of an option-pricing model from a set of observed option prices. The approach is based on a stochastic optimization algorithm, which generates a random sample from the set of global minima of the in-sample pricing error and allows for the existence of multiple global minima. Starting from an IID population of candidate solutions drawn from a prior distribution of the set of model parameters, the population of parameters is updated through cycles of independent random moves followed by "selection" according to pricing performance. It examines conditions under which such an evolving population converges to a sample of calibrated models.
