Dijkstra's algorithm in Cython, part 3/3
Running time of Dijkstra's algorithm on DIMACS networks with various implementations in Python. This post is the last part of a three-part series: first part second part In the present post, we compare the in-house implementation of Dijkstra's…
Dijkstra's algorithm in Cython, part 2/3
This post is the second part of a three-part series. In the first part, we looked at the Cython implementation of Dijkstra's algorithm. In the current post, we are going to compare different priority queue implementations, using Dijkstra's…
Dijkstra's algorithm in Cython, part 1/3
In this post, we are going to present an implementation of Dijkstra's algorithm in Cython. Dijkstra's algorithm is a shortest path algorithm. It was conceived by Edsger W. Dijkstra in 1956, and published in 1959 [1].…
A Cython implementation of a priority queue
Credit: Musée de l'illusion, Lyon [picture taken by myself] In this post, we describe a basic Cython implementation of a priority queue. A priority queue is an important data structure in…
