The least complex method for solving nonlinear programming problems is referred to as substitution. This method is restricted to models that contain only equality constraints, and typically only one of these. The method involves solving the constraint equation for one variable in terms of another.
How do you find the equation of a nonlinear line?
A non-linear graph is a graph that is not a straight line. A non-linear graph can be described by an equation. In fact any equation, relating the two variables x and y, that cannot be rearranged to: y = mx + c, where m and c are constants, describes a non- linear graph.
