A deterministic polynomial-time algorithm for formulas where the outermost sum has only a constant number of terms was obtained quite recently (2005). Webdeterministic algorithm for PIT would represent a major breakthrough in complexity theory. Along the way, we will review important concepts from graph theory and algebra. 2 …
