Definition: A priority queue implemented with a binary tree having the following restrictions:
Generalization (I am a kind of ...)
Aggregate child (... is a part of or used in me.)
binary tree, heap property.
See also leftist tree, heap.
Note: The subtree restriction means that when inserting at a leaf, the left subtree is always used before the right subtree. Favoring the left subtree tends to make the tree taller and thinner.
After [GBY91, pages 223-225].
