WebIf the graph is sufficiently sparse — in particular, E = o (V^2/lg V) — we can improve the algorithm by implementing the min-priority queue with a binary min-heap. Why should the graph be sparse? Here is another part: Each DECREASE-KEY operation takes time O (log V), and there are still at most E such operations. Suppose my graph looks like ... WebBinary Heaps. ¶ In chapter 7, the binary heap was introduced as a method to store a collection of objects in such a way that the smallest element can be quickly found. As promised, this appendix will explain the details behind this data structure. ¶ Consider again the problem we needed to solve. The A* algorithm created large amounts of small ...

WebImplementation: Extract & SiftDown. The extract operation removes the root and replace it by the left-most leaf. To recover the heap properties the siftDown is applied on the new root: if root is less than its children, then heap is satisfied and terminate, otherwise, swap the root with the minimum children and repeat recursively.
