chipfiring: A Python Package for Efficient Mathematical Analysis of Chip-Firing Games on Multigraphs
This paper presents `chipfiring`, a comprehensive Python package for the mathematical analysis of chip-firing games on finite graphs. The package provides a robust toolkit for defining graphs and chip configurations (divisors), performing chip-firing operations, and analyzing fundamental properties such as winnability, linear equivalence, and divisor rank. We detail the core components of the library, including its object-oriented graph and divisor implementations, integrated Laplacian matrix c…

The 26-year-old was arrested on June 21 at Charles de Gaulle airport at the request of the United States, which has charged him with conspiracy to commit computer fraud. According to American investigators, Kasatkin acted as an accomplice in a hacker group’s ransomware attacks on roughly 900 companies, including two federal institutions, between 2020 an…

Anyways! It was a nice ~50km loop with excellent weather (prepared with a lo…

A serene landscape scene featuring a body of water with boats gently floating on its surface. The water is surrounded by lush green trees, creating a tranquil and peaceful atmosphere. The sky above is a clear blue with white clouds adding a touch of whimsy to the scene. A single tree with full foliage stands prominently in the foreground, adding a sense of depth and perspective to the composition.
A serene scene depicting a green bicycle parked on a grey road surrounded by lush grass and tall trees. The bicycle, with its green frame and black tires, stands out against the neutral background. The road stretches into the distance, disappearing into the horizon. No people are present in the image, only the solitary bicycle.

"Aangezien XP geen backdoors heeft mbt persoonlijke data wordt het gezien als safe."
En als de Russen die Amerikaanse software veilig genoeg vinden voor zichzelf, zal dat dus ook wel kloppen.

Aangezien XP geen backdoors heeft mbt persoonlijke data wordt het gezien als safe.
