I’m happy to announce that SageMath’s matroid functionality will be improved again this summer: Zach Gershkoff, a PhD student at Louisiana State University, will work on a dedicated Graphic Matroid class, among other improvements. See the project overview here.
This marks the fourth year in a row that a Matroid project was selected by SageMath for the Google Summer of Code program. Previous participants are Tara Fife, Chao Xu, and Jayant Apte.
