space priority queuebatch markovian arrival process (BMAP)phase-type (PH) distributionThis paper applies a matrix-analytic approach to analyze both the long-term and the short-term loss behaviors of a queue with space priority scheme. Five related performance measures are derived from conditional ...

ComplexityTime: O(n log n), insertion into an array is constant but sorting takes n log n. Space: O(n), the space used in memory will grow proportionally to the number of elements in the queue.Here’s the implementation of the Enqueue method:...
下面是第一种方法,用了STL容器priority_queue来实现。当然还有很多其他方法实现。要使用这个容器的技巧就是:增加一个adaptNode相当于一个adaptor,使得可以使用priority_queue,否则因为原来的ListNode没有< >的操作而无法使用这个容器的。 #include<iostream>
Accessing elements in a priority_queue has constant complexity.There are three types of container adaptors defined by the STL: stack, queue, and priority_queue. Each restricts the functionality of some underlying container class to provide a precisely controlled interface to a standard data structure...

CBPQ: High Performance Lock-Free Priority Queue Anastasia Braginsky1(B), Nachshon Cohen2, and Erez Petrank2 1 Yahoo Research, Haifa, Israel anastas@yahoo-inc.com 2 Technion - Israel Institute of Technology, Haifa, Israel {ncohen,erez}@cs.technion.ac.il Abstract. Priority queues are an ...
The threshold k has been chosen for the queuing system in order to restrict the entrance of the low-priority customers and hence to utilize the capacity of the space priority queue more for high-priority customers. The main contributions of this paper are two-folds and will be stated in the...
