Sage Days 49 Coding Sprint Projects
For the main Sage Days 49 page go here
Below is a list of proposed projects. Please edit and add your projects!
Combinatorics
Implementing Stanley chromatic symmetric function for posets
Mathieu, Eric, Alejandro, Chris
Implementing boards for rook placements, Le diagrams (#14127)
- implementing Le diagrams
- include CombinatorialMaps if possible
- adding documentation and doctests
Alejandro
Flow polytopes from permutation matrices and alternating sign matrices (#14654)
Jessica, Alejandro
Implementation of k-tableaux and kcharge
Anne, Jennifer
Combinatorial actions and orbit averages on posets, order polytopes, and rational functions
Tom Roby, Darij, Jessica
Combinatorial Species
Martin Rubey, Thursday and Friday only
- code cleanup
- generation of unlabelled objects for composition and functorial composition via a group action framework
- multisort species (multivariate formal power series would be useful for that)
- add code by Andrew for Gamma-species
- support operations from symmetric function code for cycle index series
Conclude OEIS ticket #10358 (rebase after #13701, last doctests, and make urls clickable from the notebook
