WebOptimal control problems can be solved by a metaheuristic based algorithm (MbA) that yields an open-loop solution. The receding horizon control mechanism can integrate an MbA to produce a closed-loop solution. When the performance index includes a term depending on the final state (terminal penalty), the prediction’s time possibly surpasses a sampling … WebJan 20, 2024 · Page replaced is according to FIFO (First in First Out) The page that entered first must be swapped out first In other words, the oldest frame must be swapped out Example It might be a confusing theory, lets look with an example – Incoming page Steam – 7, 0, 1, 2, 0, 3, 0, 4, 2, 3, 0, 3, 2, 1 Page Size/ Frame Size = 3
