Abstract:
1. A method for using a computer system to solve a system of nonlinear equations specified by a vector function, f, wherein f(x)=0 represents ƒ 1 (x)=0, ƒ 2 (x)=0, ƒ 3 (x)=0, . . . , ƒ n (x)=0, wherein x is a vector (x 1 , x 2 , x 3 , . . . x n ), the method comprising: receiving a representation of an interval vector X=(X for each nonlinear equation ƒ substituting the interval vector X into the modified equation to produce the equation g(X′ solving for X′ intersecting X′ wherein the new interval vector X
