log_barrier(Problem,InnerSolver)

• Problem - Problem object implementing constrained_optimization_problem_protocol. The initial point need not be strictly feasible.

• InnerSolver - Atom naming a local_optimization solver class taking a single problem parameter, e.g. bfgs or lbfgs. Constructed dynamically each outer iteration as InnerSolver(SubProblem).

Interior-point log-barrier method for inequality constraints, optionally combined with a quadratic penalty for equality constraints.
