WitrynaI know heaps are commonly implemented by an array. But, I wanted to share my pointer implementation and have your feedback(s) :) General idea: I convert the index to its binary value and then trace the heap (0 = leftChild & 1 = rightChild)] Note: The first 1 is for entering the root. I do the push at the same time. http://www.codesdope.com/blog/article/priority-queue-using-heap/ Witryna23 cze 2013 · I've implemented a min-max heap from this paper twice (not in C) and found it fairly trivial. An improvement, which I haven't ever implemented, is a Min-Max-Fine-Heap. I can't find any good papers or references on a plain old fine heap, but I did find one on the min-max-fine-heap, which apparently performs better: graph database oracle
