[. −. ] [src] A monotone priority queue implemented with a radix heap. A monotone priority queue is a priority queue that only allows keys to be inserted if their priority is less than or equal to that of the last extracted key. In this implementation, the last extracted value is known as the "top" value.

WebJun 7, 2024 · 6. Standard Dijkstra's uses a priority queue and can handle floating-point values. This allows all the weights to differ from each other and implies no upper bound. But now you have integer weights and an upper bound: given these additional constraints you should be able to build a faster algorithm. And, indeed, you can, by using buckets (one ... WebWe implement a two level radix heap. Let k=sizeof (KeyType)*8 be the number of bits in a key. In contrast to an ordinary radix heap which contains k buckets, we maintain ceil …
