Isomorphism and Canonical Labeling of Tournaments

Speaker: V. Arvind

Room: Mathematics & Computer Building (MC) 5158

Abstract:

We give a polynomial-time oracle algorithm for canonical labeling of tournaments that accesses oracles for tournament isomorphism and for canonizing rigid tournaments. For general graphs such a result is not known. 
We'll also describe an n^{O(k^2+log n)} canonical labeling algorithm for hypertournaments with n vertices and hyperedges of size k.
