Tīmeklis2024. gada 11. sept. · Now when using Lagrangian relaxation for a minimization problem, you will most likely end up with a lower bound solution (multiplier is > 0 and penalty <= 0). My problem is understanding what is wrong with having a lower bound solution. For example, lets say I am trying to minimize some cost function and I use … TīmeklisVI-4 CHAPTER 6.
