Metaheuristics for Multiobjective Optimization
(2 hours)

This tutorial provides with a general picture of the current state-of-the-art in multiobjective optimization using metaheuristics. First, some historical background is provided, dating back to the origins of multiobjective optimization in general. This discussion motivates the use of metaheuristics for solving multiobjective problems and includes a brief description of some of the earliest approaches proposed in the literature. Then, a discussion on different heuristics used for multiobjective optimization is provided. This discussion includes evolutionary algorithms, simulated annealing, tabu search, scatter search, the ant system, particle swarm optimization and artificial immune systems. The tutorial finishes with a discussion of some of the research topics that seem more promising for the next few years.

Yaochu Jin, University of Surrey, UK

A Systems Approach to Evolutionary Aerodynamic Design Optimization
(1.5 hours)

Evolutionary algorithms (EAs) have shown to be effective in solving a wide range of test problems. However, it is not straightforward to apply EAs to complex real-world problems. This tutorial presents a systems approach to address a few major challenges we face in applying EAs to complex structural optimization, including the involvement of time-consuming and multi-disciplinary quality evaluation processes, changing environments, vagueness in formulating criteria formulation, and the involvement of multiple sub-systems. Approaches to addressing the above-mentioned issues with respect to geometry representation, genetic variations, surrogate model management, robustness and scalability are discussed in detail.

Silvia Poles, EnginSoft, Italy

Multiobjective Optimization for Innovation in Engineering Design
(1.5 hours)

ompanies daily need to optimize their products, hence optimization plays a significant role in today's design cycle. Problems related to one or more than one objective, originate in several disciplines; typically using a single optimization technology is not sufficient to deal with real-life problems, particularly when the design concerns complex and expensive products. Therefore, engineers are frequently asked to solve problems with several conflicting objective functions. The multiobjective optimization approach provides a set of non-dominant designs (Pareto optimality) where a further improvement for one objective is at the expense of all the others: this allows designers to choose the best solution for each scenario.

Solving real-world multiobjective problems is not simple, engineers must address problems connected to the non-linearity of the functions, complexity of the physics and the computational cost that snowballs as the number of parameters increases. Moreover, the coupling between disciplines for design a product can be really challenging, involving several complicating factors, such as the limitation on the computational resources, and even a lack of communication between different departments.

This tutorial is a survey on methodologies to approach design optimization process, a set of best practices intended for rapid delivery of high-quality products, with a specific focus on the numerical algorithms and post-processing used for selecting optimal design configurations.

Roberto Battiti, University of Trento, Italy

Reactive Business Intelligence and Data Mining
(2 hours)

Humans are innately visual creatures: a big portion of our brains is devoted to processing visual information. Our ancestors needed to be very fast to identify predators in the jungle. We need to be very fast to transform huge amounts of information into insight, knowledge, engineering designs, choices, decisions. Visual analytics deals with analytical reasoning facilitated by interactive visual interfaces. By the term Reactive Business Intelligence we mean the integration of interactive visual representations into the discovery and problem solving context. The search and choice task often involve a learning path between two entities: the decision maker and the supporting software system. The decision maker analyses some representative solutions, learning about concrete possibilities and updating his objectives. The software system memorizes the user preferences and modifies the internal search procedure by shifting the focus of attention onto regions of the design/solution space which are deemed more relevant by the final user. The integration of automated machine learning and optimization represents the core principle of Reactive Search Optimization. The tutorial is focussed onto extending these priciples in the area of interactive visual analytics.
