Priority queues

Randomized meldable heap

In computer science, a randomized meldable heap (also Meldable Heap or Randomized Meldable Priority Queue) is a priority queue based data structure in which the underlying structure is also a heap-ordered binary tree. However, there are no restrictions on the shape of the underlying binary tree. This approach has a number of advantages over similar data structures. It offers greater simplicity: all operations for the randomized meldable heap are easy to implement and the constant factors in their complexity bounds are small. There is also no need to preserve balance conditions and no satellite information within the nodes is necessary. Lastly, this structure has good worst-case time efficiency. The execution time of each individual operation is at most logarithmic with high probability. (Wikipedia).

Merge Sort 1 – The Algorithm

This is the first in a series of videos about the merge sort. It describes the principle of the merge sort algorithm, which takes a ‘divide and conquer’ approach to the problem of sorting and unordered list. The videos that follow build on these principles, leading towards a recursive im
