Crack LeetCode, not only how, but also why.
Do you actually use algorithms and data structures on your day to day job? I've noticed a growing trend of people assuming algorithms are pointless questions that are asked by tech companies purely as an arbitrary measure. I hear more people complain about how all of this is a purely academic exercise. This notion was definitely popularized after Max Howell, the author of Homebrew, posted his Google interview experience:
Google: 90% of our engineers use the software you wrote (Homebrew), but you can’t invert a binary tree on a whiteboard so fuck off.

Python codes implementing algorithms described in Bishop's book "Pattern Recognition and Machine Learning"
A* algorithm visualizer written in pygame.
Analyses of single-cell recordings from mouse ventral tegmental area are consistent with a model of reinforcement learning in which the brain represents possible future rewards not as a single mean of stochastic outcomes, as in the canonical model, but instead as a probability distribution.
CleverCSV provides a drop-in replacement for the Python csv package with improved dialect detection for messy CSV files. It also provides a handy command line tool that can standardize a messy file or generate Python code to import it.
Graphical A* simulation.
Collections: double linked list, deque, RBtree, channels.
The idea of RosettaGit is to present solutions to the same task in as many different programming languages as possible. It demonstrates how languages are similar and different and can help you learn new approaches to solving problems.
Normally, the arrangement of mines is decided at the start of the game (except for some trickery so that you cannot lose on the first click). But what if there was no pre-determined arrangement, and the game was allowed to choose after you play?
An interesting article describing the logic of this original minesweeper game.
TextDistance, a python library for comparing distance between two or more sequences by many algorithms.

- Optional
numpyusage for maximum speed.
Python3 implementation of the Schwartz-Hearst algorithm for extracting abbreviation-definition pairs.
PCA is a linear dimensionality reduction technique. Many non-linear dimensionality reduction techniques exist, but linear methods are more mature, if more limited.
All Algorithms implemented in Python.
