摘要

通过允许以某种形式更改队列中元素的优先级，定义了两种通用的优先级队列类型。我们证明了它们可以有效地实施。因此，每个操作需要O(log n)时间。我们利用这些广义优先级队列构造了一个O(EV log V)算法，用于在一般图中寻找最大加权匹配。

Priority queues with variable priority and an O(EV log V) algorithm for finding a maximal weighted matching in general graphs

We define two generalized types of a priority queue by allowing some forms of changing the priorities of the elements in the queue. We show that they can be implemented efficiently. Consequently, each operation takes O(log n) time. We use these generalized priority queues to construct an O(EV log V) algorithm for finding a maximal weighted matching in general graphs.
