Webb1 feb. 2024 · Simply put, the technique is to add a term to the objective function such that it produces a high cost for violation of constraints. This is known as the Penalty function method. Mathematically, where R is a penalty parameter, P (x, R) is the penalty function, and Ω is the penalty term. Webb13 okt. 2024 · You can define a penalty function, p (x), which has the property p (x) = 0 whenever g (x) ≤ 0, and p (x) > 0 whenever g (x) > 0. A common choice is a quadratic penalty such as p (x) = max (0, g (x) ) 2 .
