An Integrated View of Selection in Evolutionary Algorithms
Carlos M. Fonseca
University of Coimbra

Talk Abstract: Selection plays a double role in evolutionary algorithms. The selection of solutions from the current solution set (or population) to produce new candidate (offspring) solutions through variation is known as parental selection, whereas the selection of solutions to discard in order to make room for new solutions in the population is usually called environmental selection. Intimately related to selection is the concept of solution fitness, which is typically related to the objective function(s) of the problem at hand. In practice, both types of selection must be implemented, although different evolutionary algorithms often emphasize either one or the other. In particular, it is common for only one type of selection to depend on fitness. Selection also has the double purpose of steering the search towards more promising regions of the search space by favouring the best solutions available (exploitation) while maintaining a sufficient level of diversity in order to be able to escape local optima and/or find multiple good solutions (exploration). Over the years, many different approaches to selection in evolutionary algorithms have been proposed in the literature, with the balance between exploration and exploitation gaining heightened importance in the context of multiobjective optimization. However, parental and environmental selection have continued to be seen as different operators, and to be implemented separately. In this talk, selection methods and fitness assignment strategies are reviewed and discussed from the unifying perspective of portfolio optimization, where the fitness of a solution is interpreted as an investment in that solution, and solution diversity emerges naturally from the need to balance return and risk in the portfolio. In addition, parental and environmental selection can be seamlessly integrated in the portfolio optimization formulation. Application examples illustrate the main aspects of the approach.

Oussama Khatib

Talk Abstract: The promise of oceanic discovery has intrigued scientists and explorers for centuries, whether to study underwater ecology and climate change, or to uncover natural resources and historic secrets buried deep at archaeological sites. The quest to explore the ocean requires skilled human access. Reaching these depth is imperative since factors such as pollution and deep-sea trawling increasingly threaten ecology and archaeological sites. These needs demand a system deploying human-level expertise at the depths, and yet remotely operated vehicles (ROVs) are inadequate for the task. A robotic avatar could go where humans cannot, while embodying human intelligence and intentions through immersive interfaces. To meet the challenge of dexterous operation at oceanic depths, in collaboration with KAUST's Red Sea Research Center and MEKA Robotics, we developed Ocean One, a bimanual force-controlled humanoid robot that brings immediate and intuitive haptic interaction to oceanic environments. Teaming with the French Ministry of Culture’s Underwater Archaeology Research Department, we deployed Ocean One in an expedition in the Mediterranean to Louis XIV’s flagship Lune, lying off the coast of Toulon at ninety-one meters. In the spring of 2016, Ocean One became the first robotic avatar to embody a human’s presence at the seabed. This expedition demonstrated synergistic collaboration between a robot and a human operating over challenging manipulation tasks in an inhospitable environment. Tasks such as coralreef monitoring, underwater pipeline maintenance, and offshore and marine operations will greatly benefit from such robot capabilities. Ocean One’s journey in the Mediterranean marks a new level of marine exploration: Much as past technological innovations have impacted society, Ocean One’s ability to distance humans physically from dangerous and unreachable work spaces while connecting their skills, intuition, and experience to the task promises to fundamentally alter remote work. We foresee that robotic avatars will search for and acquire materials in hazardous and inhospitable settings, support equipment at remote sites, build infrastructure for monitoring the environment, and perform disaster prevention and recovery operations— be it deep in oceans and mines, at mountain tops, or in space

Talk Abstract: Unmanned Aerial Systems (UAS) have become an essential tool in several civilian and industrial applications. However, there still exist a strong dependency on a pilot for the UAS to be operated and deployed. Applications such as inspection, exploration or monitoring require the execution of several flight mission that may turn tedious and tiresome to the operator, prone to human failure with catastrophic results. In recent years, Artificial Intelligent (AI) has been leveraged by the revival of Neural Networks (NN), but in particular, by a type of NN that exploits parallel computing implementations on Graphics Processing Units (GPUs), namely the Convolutional Neural Networks, whose implementation through several layers have given rise to what is known now as Deep Learning (DL). With impressive results in domains where the combinatorial factor exploded, DL has shed light by enabling the development of solutions that can even run in real time. Thus, the field of autonomous UAS, this is without operator, has not been an exception to the use of DL, especially for the development of methods that enable a UAS to take autonomous intelligent decisions. In this talk, a number of examples involving DL and intelligent UAS will be presented. In this spirit, It will be discussed how current state of the art challenges can be better tackled with the DL-based technology. The talk will conclude with some remarks and forecasts on how DL will also leverage the future of the next generation of intelligent UAS.

A novel multi-objective evolutionary algorithm with fuzzy logic based adaptive selection of operators: FAME
Héctor Joaquín Fraire-Huacuja
Instituto Tecnológico de Ciudad Madero

Talk Abstract:We propose a new method for multi-objective optimization, called Fuzzy Adaptive Multi-objective Evolutionary algorithm (FAME). It makes use of a smart operator controller that dynamically chooses the most promising variation operator to apply in the different stages of the search. This choice is guided by a fuzzy logic engine, according to the contributions of the different operators in the past. FAME also includes a novel effective density estimator with polynomial complexity, called Spatial Spread Deviation (SSD). Our proposal follows a steady-state selection scheme and includes an external archive implementing SSD to identify the candidate solutions to be removed when it becomes full. To assess the performance of our proposal, we compare FAME with a number of state of the art algorithms (MOEA/D-DE, SMEA, SMPSOhv, SMS-EMOA, and BORG) on a set of difficult problems. The results show that FAME achieves the best overall performance.

New hybrid optimization methods for bin-packing problems
Laura Cruz Reyes

Talk Abstract: Cloud computing is a new scenario that is taking a lot of importance to improve the traditional management of organizations, and of society in general. In this context, a key aspect is to find planning strategies that allow efficient use of resources. Among these strategies is the placement of resources in the cloud that can be modeled as a problem of accommodating objects. Other real scenarios can also be modeled in this way, hence the importance of the classic problem of accommodating objects in containers called BPP (Bin Packing Problem). This problem belongs to the NP-hard class, so it is considered unsolvable in polynomial time. For problems of this kind, the search for efficient algorithms is an area in constant evolution. In this talk, the most outstanding hybrid approaches of the state of the art for the BPP solution will be presented, emphasizing the optimization methods based on evolutionary grouping and virtual savant. The last one is a new paradigm based on machine learning to automatically generate parallel solvers that have learned how to solve a problem.
