TīmeklisWe define next the problem dual to (P), via our augmented Lagrangian function. Definition 3.5 (augmented Lagrangian and associated dual problem) With the notation of Problem (P), let (a) fbe a dualizing parameterization as in Definition 3.1, satisfying assumption (H2), (b) A: H→ Hbe a function verifying the assumptions (A0)–(A1). Tīmeklis这样,原问题 primal problem可以通过解另外一个问题 dual problem 得到原最优解的一个下界,有时甚至可以得到最优解,此转化的诱人之处部分在于,primal problem 中棘手的约束条件在 dual problem 中不复存在。因此,duality 有着很重要的意义。 how to paint varnished wood doors white https://prestigeplasmacutting.com
