D ary heap - Give an efficient implementation of INSERT in a d-ary max-heap. Analyze its running time in terms of d and n. Give an efficient implementation of INCREASE-KEY(A, i, k), which flags an error if k < A[i] = k and then updates the d-ary matrix heap structure appropriately.

 
The d-ary heap data structure is a generalization of a binary heap in which each node has d children instead of 2. This speeds up "push" or "decrease priority" operations ( O(log n / log d) ) with the tradeoff of slower "pop" or "increase priority" ( O(d log n / log d) ). . Muzzleloader kit cabela

May 6, 2015 · 1. In a d-ary heap, up-heaps (e.g., insert, decrease-key if you track heap nodes as they move around) take time O (log_d n) and down-heaps (e.g., delete-min) take time O (d log_d n), where n is the number of nodes. The reason that down-heaps are more expensive is that we have to find the minimum child to promote, whereas up-heaps just compare ...
