This book contains the latest advances in variational analysis and set / vector optimization, including uncertain optimization, optimal control, and bilevel optimization. In addition, recent developments concerning scalarization techniques, necessary and sufficient optimality conditions and duality statements are discussed. These new numerical methods help practitioners efficiently solve set optimization problems in real-world situations. Moreover, applications in economics, finance and risk theory are discussed. These simple techniques are designed to help practitioners in the decision-making process, as well as to give an overview of nondominated solutions to choose from.
