Providing Better Choices: An Exploration of Solutions in Multi-Objective Optimization and Game Theory Using Variational Analysis
by Harris, Glenn Matthew, Ph.D., Northern Illinois University, 2020, 152; 27961425
Abstract (Summary)

Multi-objective optimization problems and game theory problems have a wide array of applications and because of this there are different types of solutions available. This dissertation explores two areas of optimization and a solution type for each. First, substantial efficiency (SE) as a type of solution to multi-objective optimization problems that extends proper efficiency. Secondly, strong Nash equilibria (SNE) as a type of solution to game theoretic problems that extends Nash equilibria. Substantial efficiency is demonstrated to be a superior solution to the more rudimentary notion of proper efficiency in solving some multi-objective financial market and economic problems. Using this as motivation, a careful examination is given for SE solutions in linear multi-objective optimization problems. Examples are given showing that SE solutions are non-trivial and may not always exist. A method for testing for substantial efficiency is provided. Existence of a SE solution can also be guaranteed in a specific context. Both a topological inspection and recession analysis are provided for the set of SE solutions. A situation where a SNE can be guaranteed is provided. An algorithm is also provided that when convergent will be to a SNE.
