Problem reduction algorithm

WebbThis lecture continues the discussion of curve fitting, emphasizing the interplay among theory, experimentation, and computation and addressing the problem of over-fitting. It then moves on to introduce the notion of an optimization problem, and illustrates it using the 0/1 knapsack problem. Image courtesy of kob42kob on Flickr.
