The Karatsuba algorithm, first published in 1962, aims to speed up the multiplication of big numbers by reducing the number of 'single-digit-multiplications' involved.Because of its complexity (...

the following is an implementation of the standard Metropolis Hastings Monte Carlo sampler. You can read more about it here.At the end I am going to give you a link to the Rust playground, so you ...

I have written the following function to be a general "error logging" solution for my Windows API projects. Basically, given a Windows system error code (a la ...

I've taken a crack at implementing Simple Diff in Rebol (versions 2 and 3). Simple Diff works by finding the longest common sequence in two series, then recursively applies itself either side of this ...

Follow up to Selection sort with reduced comparison count - semi-final Iteration?My goal (and excuse not to tag reinventing…) is to have presentable code to argue the viability of reducing the number ...

Inspired by this post I looked up A* on wikipedia and went on with my own implementation as seen below where I try to mimic the pseudocode on Wikipedia but in a recursive manner. I would like any ...

I've written a red-black tree in C as an exercise. The tree works and it is not bad, but it is about 10% slower thanstd::multimap from libstdc++ which I'm ...

For a side project, I needed a markdown parser and I decided to roll my own.It is a SAX-style parser, i.o.w. you can hook into parser events on consumer side and do whatever you want with the content....

Language:The Brainfuck programming language consists of eight commands:...

Related: Find all distinct subsets that sum to a given numberThis code is supposed to efficiently generate all subsets of a list such that the subset's values sum to a particular target value. For ...

Here is a project that I worked on for a few days in June 2020. Since the algorithm is extremely slow, I looked into methods in order to parallelize operations but did not obtain any satisfactory ...

I created a small-ish NodeJS script which takes as argument the name of a Wikipedia article (and optionally a Wikipedia edition, "en" is default) and creates a Git repository with each ...

I found a post I made here an year ago (Compiler for a minimal LISP dialect to run on the Java Virtual Machine) and got interested on this subject again. This time I decided to implement the ...

The code implements fully generic sliding window with linear complexity. It should usually be paired with transforming iterator to reach full potential.Sliding window is a grouping of elements by ...

I recently coded this FNV-1a hash function in Lua. Are there any apparent performance improvements that could be implemented?...
