**Suggested Syllabus****Preparatory reading:**Russell and Norvig reading listed above**Class 1:**Define problem, terminology, cover and collectively implement simple hill climbing (through "Hill Descent" in Teaching Stochastic Local Search)**Class 2:**Observe local minima, add random uphill steps, add simulated annealing step, play with demo applets above (remainder of Teaching Stochastic Local Search)**Homework:**Assign one or more challenge problems (see "Challenge Problems" of Teaching Stochastic Local Search)**Optional Laboratories:**Give a simple, engaging combinatorial optimization problem, and have students (1) formalize the problem (clearly stating assumptions, constraints, etc.), (2) implement the associated annealing State, and (3) apply the stochastic local search method of their choice. Have students justify their choices of optimization measures, discussing advantages and disadvantages to their problem formalizations. Also, given time, have students demonstrate their software. Here are two suggested challenge problems:**Forming teams**: Forming project teams is a difficult task for faculty. While some choose to form teams randomly, others seek to optimize various subjective/objective measures. Write software that will optimize course project teams according to objective measures of your choice (e.g. maximizing students working with those they prefer, balancing group sizes, balancing abilities, etc.). Justify your choice of measures, discussing advantages and disadvantages to your problem formalization.**Ordering pizza**: Pizza is an important food group of computer science departments everywhere. Write software that will optimize pizza ordering according to objective measures of your choice (e.g. maximizing diners getting preferred toppings, minimizing waste, etc.). Justify your choice of measures, discussing advantages and disadvantages to your problem formalization.
