This project is about formally verifying Seymour's decomposition theorem for regular matroids.
matroids in lean
Matroid Chow Rings, and their semi-small decompositions.
Discrete Mathematics course at ITMO University
Compute arboricity and forest decomposition of graphs.
Python interface to matroid database
Code accompanying the pre-print "Computing Algebraic Matroids" by Zvi Rosen.
SageMath functions manipulating conditional oriented matroids. Among other functions, the check if a set corresponds to a conditional oriented matroid, the generating of that latter from its tope set, its Varchenko determinant computing, and the solving of its Aguiar-Mahajan system are implemented.
document about matroid theory
A small Python package to perform computations on graphic matroids.
Discrete Math Labs
Random matroid generator, circuit sampler, exploring the clustering phenomena and phase transitions
Add a description, image, and links to the matroids topic page so that developers can more easily learn about it.
