CHABIS
Algorithm 666. CHABIS: A mathematical software package for locating and evaluating roots of systems of nonlinear equations. CHABIS is a mathematical software package for the numerical solution of a system of n nonlinear equations in n variables. First, CHABIS locates at least one solution of the system within an n-dimensional polyhedron. Then, it applies a new generalized method of bisection to this n-polyhedron in order to obtain an approximate solution of the system according to a predetermined accuracy. In this paper we briefly describe the user interface to CHABIS and present several details of its implementation, as well as an example of its usage
