"Compositional Algorithms on Compositional Data: Deciding Sheaves on Presheaves" — ACT 2023, Benjamin Merlin Bumpus et al.
"any computational problem which can be represented as a sheaf with respect to these topologies can be decided in linear time on classes of inputs which admit decompositions of bounded width" — arXiv:2302.05575
Key Insight: Structured decompositions define Grothendieck topologies on categories of data (adhesive categories). This leads to algorithms on objects of any C-set category - structures such as: symmetric graphs, directed graphs, hypergraphs, databases, simplicial complexes, port graphs.
