Heap Structures

---

Detailed Description

This group contains the heap structures implemented in LEMON.

LEMON provides several heap classes. They are efficient implementations of the abstract data type priority queue. They store items with specified values called priorities in such a way that finding and removing the item with minimum priority are efficient. The basic operations are adding and erasing items, changing the priority of an item, etc.

Heaps are crucial in several algorithms, such as Dijkstra and Prim. The heap implementations have the same interface, thus any of them can be used easily in such algorithms.
