The article discusses how pricing algorithms, even simple ones, can lead to higher prices through unintended collusion in a market. It highlights recent research showing that algorithms can learn to raise prices without explicit coordination, complicating the regulatory landscape for fair pricing. The challenges of ensuring fair prices in the era of algorithmic pricing are examined through the lens of game theory.

The article discusses the formation of fingerprints, likely exploring the underlying biological and physical processes that lead to the unique patterns observed in human fingerprints. It may also include numerical algorithms and results related to the modeling of fingerprint development.

The article discusses the technique of dithering in image processing, explaining its importance for reducing color depth in images while maintaining visual quality. It covers eleven dithering algorithms, including the well-known Floyd-Steinberg method, and provides insights into how dithering can improve the representation of images on devices with limited color capabilities. The author emphasizes dithering's ongoing relevance in both practical and artistic applications.

The article discusses modern perfect hashing for strings, focusing on an implementation that improves upon traditional hash tables by using fixed sets of strings mapped to predefined integers. It highlights the challenges of optimizing for different architectures and provides a coding example demonstrating the use of a "magic" number to avoid collisions in hashed values.
