You have to make what seems to be a simple decision... what is the right price for your product? What is the best technology for a job?
Perhaps you are designing a new material where you want to maximize strength. You have to play with temperatures, concentrations, and ratios.
Or you are trying to optimize the performance of a company through expensive computer simulations. You can tune fleet sizes and inventories, locations of facilities, and the type of equipment you are using.
Optimal learning allows business to make these decisions in minimal time with minimal costs.
