Express middleware to correct typos in URLs via string similarity algorithms

filter the array of string/json objects using Rabin Karp algorithm

A generic search algorithm for complex objects

Quartz plugin to render pseudocode at build-time using pseudocode.js. Works transparently with the Obsidian plugin obsidian-pseudocode.

secure-caesar cipher, is a symetric key cipher, based on caesar shift cipher. Enhanced with unicode support, custom padding, Scrypt key expander, elliptic curve support & power usage selection.

A utility class for binary search operations in JavaScript

Set array items declaratively

配合RDK硬件使用视觉算法的Node-RED功能包(Node-RED nodes for using vision algorithms on a RDK hardware)

a Node.JS implementation for AStar path finding algorithm. This implementation uses primitive data types (Number and Byte/Buffer) to present location and block data that significantly improve the speed and have a good control on memory consumption

A Node-RED node that demonstrates the use of the Knapsack algorithm

Heap data structure for JavaScript / TypeScript.

This is an ongoing project intended to make it easier to use neural network creation, genetic algorithms, and other data science and machine learning skills.

An ES module with a class providing a "Pseudo-random number generator" which is "pluggable" meaning you can plug-in any PRNG algorithm. It's also "seedable" meaning that it can have a reproducible (deterministic) output based on its starting seed. The mod

Compute a percentage repartition based on possibly fixed percentage values in a dataset

A quite fast non-recursive permutation algorithm, Steinhaus–Johnson–Trotter algorithm (Even's speedup)

A tiny and fast perceptual image hashing algorithm

Potsiu! is a simple utility function that allows you to update indexes of specific positions on a string after you apply some transformation to it. It is quite handy if you have data in which string indexes are specified, but for some reason you want to p
