# What are the (general) sizes of AlphaGo and Deep Blue?

I'm trying to get a gauge on just how big the programs and databases are these automata. I understand that this is a changing number, particularly in regard to Machine Learning.

Q: How large was Deep Blue when it beat Gary Kasparov?

Q: How big was AlphaGo when it beat Lee Sedol?

• Let's get the concepts correct. AlphaGo uses Monte-Carlo Tree Search, it doesn't prune. Also, we don't prune a database, we search from it. We prune a search tree, like the alpha-beta algorithm. – SmallChess Mar 31 '17 at 0:13
• @StudentT thanks for the correction. (I've amended the question to remove the problematic language.) – DukeZhou Apr 1 '17 at 19:48
