Nonlinear Programming

Nonlinear programming (NLP) is a method used in optimization, where the goal is to find the best solution to a problem that involves variables with relationships that are not straight lines (i.e., nonlinear). Unlike linear programming, where changes in one variable produce proportional changes in the outcome, NLP deals with more complex interactions that can involve curves and other shapes. It's widely applied in various fields such as engineering, finance, and logistics, helping to optimize outcomes like minimizing costs or maximizing efficiency when relationships between factors are intricate and interconnected.
