Module summary
Optimisation ''the quest for the best'' plays a major role in financial and economic theory, e.g. in maximising a company's profits or minimising its production costs. How to achieve such optimality is the concern of this course, which develops the theory and practice of maximising or minimising a function of many variables, either with or without constraints. This course lays a solid foundation for progression onto more advanced topics, such as dynamic optimisation, which are central to the understanding of realistic economic and financial scenarios.Objectives
To provide a collection of theoretical and algorithmic techniques for determining optimal extrema of arbitrary functions of several variables, either with or without constraints.On completion of this module, students should be to:
(a) determine the definiteness of quadratic forms;
(b) determine exactly extrema of functions of several variables, with or without constraints, using Lagrange multipliers;
(c) use the calculus of variations to determine extrema of integrals dependent upon one or more arbitrary functions;
(d) determine approximately extrema of functions of several variables, with or without constraints, using a selection of search algorithms.
