LEARNING OBJECTIVES. Explain the Monte Carlo method. Explain extreme pathways. Explain sampling low-dimensional solution space. Explain sampling . high-dimensional . solution space. Each student should be able to:. Dr. Ron Lembke. Formulating in Excel. Write the LP out on paper, with all constraints and the objective function.. Decide on cells to represent variables.. Enter coefficients of each variable in each constraint in a block of cells.. An optimization problem is a problem in which we wish to determine the best values for decision variables that will maximize or minimize a performance measure subject to a set of constraints. A feasible solution is set of values for the decision variables which satisfy all of the constraints. Dr. Ron . Lembke. Motivating Example. Suppose you are an entrepreneur making plans to make a killing over the summer by traveling across the country selling products you design and manufacture yourself. To be more straightforward, you plan to follow the Dead all summer, selling t-shirts.. Introduction.
