Day 21

We did the proof of the Chernoff Bounds. Here is a detailed write-up.

We also discussed the polynomial identity testing question: Given a polynomial p(x1,...,xn) described by a circuit of product and sum gates, is that polynomial exactly zero?

To give a probabilistic algorithm for polynomial identity testing we looked at the Schwartz-Zippel lemma and gave part of the proof.
