Non-linear Constraints

Non-linear constraints are rules or conditions in a problem that involve relationships between variables expressed by equations or inequalities with variables raised to powers or involving functions like exponents, logarithms, or trigonometry. Unlike linear constraints, which form straight-line relationships, non-linear constraints can create curved or more complex shapes. They are common in real-world problems such as optimizing designs, economics, or engineering, where relationships are rarely straight lines. Managing non-linear constraints requires more advanced methods, but they allow models to accurately represent complex, realistic scenarios.
