The d-ary heap, also known as the d-heap, is a priority queue data structure that is a generalisation of the binary heap with d children instead of two. A binary heap is a two-heap, while a ternary heap is a three-heap. Donald B. Johnson invented d-ary heaps in 1975, according to Tarjan and Jensen et al. At the cost of slower delete minimum operations, this data structure allows decrease priority operations to be done more rapidly than binary heaps. For algorithms like Dijkstra’s algorithm, where decrease priority operations are more popular than delete min operations, this tradeoff results in faster running times.
