Network Flow
Professor Guenin going over a max flow problem.
From where I sit, this is what a network flows class looks like. Currently, we are studying max st-flows. The class isn't the most interesting, though I do like it a lot more then linear optimization. For those who don't know, a max st-flow problem can be thought of as trying to find the maximum amount of liquid that can flow through a network of pipes over a period of time.
