%description
Implements an algorithm for fitting a generative model with an intractable
likelihood using only box constraints on the parameters.  The implemented
algorithm consists of two phases. The first phase (global search) aims to
identify the region containing the best solution, while the second phase
(local search) refines this solution using a trust-region version of the
Fisher scoring method to solve a quasi-likelihood equation. See Guido
Masarotto (2025) <doi:10.48550/arXiv.2511.08180> for the details of the
algorithm and supporting results.
