priority_queue的核心接口主要由成员函数push(),top(),pop()组成: push() 将一个元素置入priority_queue内. pop() 移除priority_queue中“优先级最高”的元素,如果存在多个相等的元素,则无法确知会移除哪一个. 调用者保证priority_queue非空. 该函数无返回值,想处理被移除的元素,需要调用top(). top() 从pri...

Thepriority_queueorders the sequence it controls by calling a stored function object of classTraits. In general, the elements need be merely less than comparable to establish this order: so that, given any two elements, it may be determined either that they're equivalent (in the sense that ...

CBPQ: High Performance Lock-Free Priority Queue 463 Fig. 1. Overview of the CBPQ data structure When an internal chunk is filled due to insertions, it is split into two half- full chunks using the lock-free freezing mechanism of [3]. The CBPQ scheme is illustrated in Fig. 1 (with ...
The binary heap of Williams (1964) is a simple priority queue characterized by only storing an array containing the elements and the number of elements $n$ - here denoted a strictly implicit priority queue. We introduce two new strictly implicit priority queues. The first structure supports ...
the functional queue storing in memory a highest priority enqueued item at a head of the functional queue; modifying at run time the sort criteria in memory while the functional queue contains the enqued items in memory; and re-prioritizing the enqued items in the functional queue at run time...
