More Heapsort in Cython
This post/notebook is the follow-up to a recent one : Heapsort with Numba and Cython, where we implemented heapsort in Python/Numba and Cython and compared the execution time with NumPy heapsort. However, heapsort in NumPy is written in C++…
Heapsort with Numba and Cython
Updated April 20, 2022 following usefull comments by @scoder. Thank you very much for your pull requests! Heapsort is a classical sorting algorithm. We are going into a little bit of theory about the algorithm, but refer to Corman et al. [1] for…
Merge Sort with Cython and Numba
In this post, we present an implementation of the classic merge sort algorithm in Python on NumPy arrays, and make it run reasonably "fast" using Cython and Numba. We are going to compare the run time with the numpy.sort(kind='mergesort')…
Cython and Numba applied to a simple algorithm: Insertion sort
The aim of this notebook is to show a basic example of Cython and Numba, applied to a simple algorithm: Insertion sort. As we will see, the code transformation from Python to Cython or Python to Numba can be really easy [specifically for the…
