I am starting a series of post to introduce some useful higher order functions that go hand-in-hand with the... Continue Reading →

Accumulating your merge sort

In the previous post, we described an elegant algorithm that allows to stable sort a container based on fold (also known as std::accumulate or reduce). To make it simpler, we implemented it in Haskell and used it to merge lists. The subject of today's post is to: Implement this algorithm in C++ Make it work... Continue Reading →

Folding your merge sort

Back in September 2016, I was lucky enough to attend a talk from Ben Deane entitled std::accumulate: Exploring an Algorithmic Empire. In this talk, he presents the unknown possibilities of std::accumulate, an algorithm also known as fold or reduce depending on the language. The arguments were already quite compelling... then came the slide in which... Continue Reading →
