Webb5 sep. 2014 · All penalty methods are computationally appealing, as they yield unconstrained problems for which a vast range of highly effective algorithms are available. In finite-dimensional optimization, outstanding algorithms have resulted from the careful analysis of the choice of penalty functions and the sequence of weights. 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 . You then maximize the penalized objective function q (x;λ) = f (x) - λ p (x) for a large value of the penalty parameter, λ.
