Session Overview
This 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. |

Check Yourself
What does an optimization problem consist of?
› View/hide answer
An optimization problem requires that an objective function be optimized, either by maximizing or minimizing the function. There may also be a set of constraints that must be accounted for.
What is problem reduction?
› View/hide answer
Taking a problem with an unknown solution and reducing it to a problem or problems with known solutions.
Problem Sets
Problem Set 8: Simulating The Spread of Disease and Virus Population (Due)
In this problem set, using Python and pylab you will design and implement a stochastic simulation of patient and virus population dynamics, and reach conclusions about treatment regimens based on the simulation results.
