Nonlinear programming

Nonlinear programming is a way to solve a mathematical optimization problem. A number of equations and inequalities defines such a system. They are called constraints. Nonlinear programming is similar to linear programming, except that the functions and constraints are non-linear.

  The blue region is the feasible region. The tangency of the line with the feasible region represents the solution. The line is the best achievable contour line (locus with a given value of the objective function).

  The tangency of the top surface with the constrained space in the center represents the solution.
