关于ADT优先队列(Priority Queue),以下简称为PQ,的实现方式以及Running time complexity。优先队列是根据优先级决定的抽象数据结构,一个元素会含有本身的值,和优先级。优先队列的功能有三个,Insert(PQ, x, priority), FindMax(PQ), ExtractMax(PQ)。 1. Insert(PQ, x, priority)是插入元素到样本空间中,这个...
Create new priority queue. You can pass array to initialize queue with O(n) complexity (implemented with batchenq, see below). First argument also could be an ordering function defining higher priority or you can simply pass "min" for min-heap( default behavior ) or "max" for max-heap ...
The method of priority queue first-in-first-out, automatic sorting, etc are adopted to rank the paths in real time with the possible option of U-turn strategy. Consequently,the above-mentioned method not only reduces the complexity of the shortest path algorithm but also better reflects the ...

FCFS, SJF and RR algorithm: First, arrival request of tasks is fulfilled in first come first serve (FCFS) (Li and Shi, 2009) algorithm and next demand will be in queue until first task is completed but algorithm failed to balance the workload among the virtual machines (VMs).R. K. Mo...
A natural alternative is to let customers pay and upgrade to priority at any time during their stay in the queue, even if they choose not to do so initially. This paper builds a queueing-game-theoretic model that explicitly captures self-interested customers’ dynamic in-queue priority-...
So, a high global priority task could be blocked by lower global priority tasks ahead of it in the local priority FIFO queue. This causes priority inversion and affects the schedulability of tasks with higher global priority. In addition, the optimal priority assignment requires a search of ...
before lower priority ones. Hence, retrieval of the highest priority QI always takes the same amount of time, independent of the number of items queued and independent of the number of sort criteria, because retrieving the next item always amounts to getting the top/head item of the queue. ...
time priority; taking a packet out from a first flow queues in said APQ when no backlogged flow queue has a positive ARBC and adjusting the AEBC of said flow queue by the packet scheduler; removing a flow queue from said APQ when either said flow queue becomes empty or the AEBC of ...
