In this paper we prove several new lower bounds on the maximum number of leaves of a spanning tree of a graph related to its order, independence number, local independence number, and the maximum order of a bipartite subgraph. These new lower bounds were conjectured by the program Graffiti.pc, a variant of the program Graffiti. We use two of these results to give two partial resolutions of conj...

This paper provides some history of the development of the conjecturemaking computer program, Graffiti. In the process, its old and new heuristics are discussed and demonstrated.
