The named branches are algebraic, enumerative, existential, extremal, geometric and probabilistic combinatorics, and graph theory sits inside that.

Conferences and workshops go through a separate solicitation. Proposals for them have to arrive at least six months before the event, and NSF asks for them to be in the same fiscal …
