# AF-heap

In computer science, the AF-heap is a type of priority queue for integer data, an extension of the fusion tree using an proposed by M. L. Fredman and D. E. Willard. Using an AF-heap, it is possible to perform m insert or decrease-key operations and n delete-min operations on machine-integer keys in time O(m + n log n / log log n). This allows Dijkstra's algorithm to be performed in the same O(m + n log n / log log n) time bound on graphs with n edges and m vertices, and leads to a linear time algorithm for minimum spanning trees, with the assumption for both problems that the edge weights of the input graph are machine integers in the transdichotomous model.

Understanding Java Garbage Collector and Heap | Java Garbage Collection Tutorial | Edureka

( Java Training - https://www.edureka.co/java-j2ee-training-course ) The video mainly explains heap and garbage collector. Heap is the memory area in JVM where objects are created. Garbage Collector is a special thread, which clears the memory area during runtime, freeing it from the objec
