Summation of Floating-Point Numbers in Cython
Adding up a list of floating-point numbers: seems simple. IEEE 754 double-precision floats (float64) carry about 15 to 17 significant decimal digits, and…
Visualizing the Ulam Spiral with Python
The Ulam spiral arranges integers in a spiral and highlights prime numbers, revealing some diagonal alignment patterns.
Dijkstra's algorithm in Cython, part 3/3
Running time of Dijkstra's algorithm on DIMACS networks with various implementations in Python.
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.
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.
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.
Visualizing some polynomial roots with Datashader
Last week-end I found this interesting tweet by sara: The above figure shows all the complex roots from the various polynomials of degree 10 with…
Forward and reverse stars in Cython
This notebook is the following of a previous one, where we looked at the forward and reverse star representations of a sparse directed graph in pure…
