This paper presents a comprehensive survey of methods which can be utilized
to search for solutions to systems of nonlinear equations (SNEs). Our
objectives with this survey are to synthesize pertinent literature in this
field by presenting a thorough description and analysis of the known methods
capable of finding one or many solutions to SNEs, and to assist interested
readers seeking to identify solution techniques which are well suited for
solving the various classes of SNEs which one may encounter in real world
applications.
To accomplish these objectives, we present a multi-part survey. In part one,
we focused on root-finding approaches which can be used to search for solutions
to a SNE without transforming it into an optimization problem. In part two, we
introduce the various transformations which have been utilized to transform a
SNE into an optimization problem, and we discuss optimization algorithms which
can then be used to search for solutions. We emphasize the important
characteristics of each method, and we discuss promising directions for future
research. In part three, we will present a robust quantitative comparative
analysis of methods capable of searching for solutions to SNEs.
