Detailed Description

Abstract class that provides a common interface for different Solvers.

The different Solver implementations each use a different nonlinear problem solving library, which could lead to differences in performance for various problem types. This base class allows the different Solver implementations to be swapped out with each other quickly and easily to help with testing, benchmarking, and experimentation.
