The general heap order must be enforced; Every operation (add, remove_min, merge) on two skew heaps must be done using a special skew heap merge. A skew heap is a self-adjusting form of a leftist heap which attempts to maintain balance by unconditionally swapping all nodes in the merge path when merging two heaps. (The merge operation is also ...
In addition to the heap property, leftist trees are maintained so the right descendant of each node has the lower s-value. The height-biased leftist tree was invented by Clark Allan Crane. [2] The name comes from the fact that the left subtree is usually taller than the right subtree. A leftist tree is a mergeable heap. When inserting a new ...
Leftist tree; Pairing heap; Skew heap; A more complete list with performance comparisons can be found at Heap (data structure) § Comparison of theoretic bounds for variants. In most mergeable heap structures, merging is the fundamental operation on which others are based. Insertion is implemented by merging a new single-element heap with the ...
This heap node is the root node of a heap containing all elements from the two subtrees rooted at Q1 and Q2. A nice feature of this meld operation is that it can be defined recursively. If either heaps are null, then the merge is taking place with an empty set and the method simply returns the root node of the non-empty heap.
// Perform a down-heap or heapify-down operation for a max-heap // A: an array representing the heap, indexed starting at 1 // i: the index to start at when heapifying down Max-Heapify(A, i): left ← 2×i right ← 2×i + 1 largest ← i if left ≤ length(A) and A[left] > A[largest] then: largest ← left

A pairing heap is either an empty heap, or a pairing tree consisting of a root element and a possibly empty list of pairing trees. The heap ordering property requires that parent of any node is no greater than the node itself. The following description assumes a purely functional heap that does not support the decrease-key operation.
