ABSTRACT: This report discusses the development of a stand alone
software package for solving large systems of nonlinear equations.
This work continues the development effort toward a solving capability
for the ASCEND mathematical modeling environment, and is based on a
linear equation solver that we have previous developed. Readability,
modularity, flexibility, and portability were the issues given top
priority in the solver's design. Our chosen software/hardware platform
was Pascal on an Apollo workstation. Although efficiency was also a
concern, modularity took precedence; it was important for the software
to easily incorporate multiple solving strategies.
