Helena was invited to give a talk on “ILS, Hybrid ILS … and other extensions” at the workshop Fred80fest: Innovations in Optimization and Applications, in Boulder, Colorado (March 2017). This workshop was organized by Manuel Laguna, Gary Kochenberger David Woodruff in honor of Fred Glover. Fred has devoted his academic life to innovation, particularly in the area of optimization. The purpose of this workshop is to celebrate his accomplishments and discuss innovations that are enabling the solution of complex optimization problems in practical settings.
Helena Ramalhinho is one of the Plenary Speakers of the 10th International Workshop on Hybrid Metaheuristics
The title of the talk is “From ILS to Hybrid ILS … and other extensions“.
Abstract: Iterated Local Search (ILS) is a conceptually simple and efficient Metaheuristic. The main idea behind ILS is to drive the search not on the full space of all candidate solutions but on the solutions that are returned by some underlying algorithm, typically a local search heuristic. This method has been applied to many different optimization problems with more than 5,000 entries in Google Scholar. In this talk, we will review briefly the ILS method and focus on the extensions of ILS as the hybrid ILS approaches, the different hybridizations implementations and the advantages and disadvantages of these hybridizations. We will also discuss other ILS extensions as the SimILS (Simulation+ILS) to solve Stochastic Combinatorial Optimization Problems, and the MoILS, to solve Multiobjective Combinatorial Optimization Problems. In addition, we will review the most important applications of ILS and extensions in different areas, from Supply Chain Management to Health Care. Finally, future research topics will be presented.
Helena Ramalhinho was one of the members of the panel session of the 83rd EURO Working Group on Multicriteria Decision Aiding (EWG-MCDA) organized by the Research Group on Knowledge Engineering, ESADE with the topic:
