Applications and Extensions of the Iterated Local Search

Transmissão através de Videoconferência

Por Helena Ramalhinho Lourenço (Universidade Pompeu Fabra, Barcelona).

Iterated Local Search (ILS) is a conceptually simple and efficient well-known 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, local optimal solutions obtained by the application of a local search heuristic. This method has been applied to many different optimization problems having more than 10,000 entries in Google Scholar. In this talk, we will review briefly the ILS method emphasizing the extensions of ILS. We will describe three relevant types of extensions: the hybrid ILS approaches combining ILS with other metaheuristics and/or exact methods; the SimILS (Simulation+ILS) to solve Stochastic Combinatorial Optimization Problems. We will discuss the advantages and disadvantages of these extensions and present some applications, including real ones in areas like Supply Chain Management, Economic Development or Health Care. Finally, future research topics will be presented.

The objective of this course is to acquire knowledge regarding bioinformatic tools available to predict nucleic acid (RNA, DNA or Nucleic Acids Mimics) and protein three-dimensional structure, as well as autonomy and critical thinking in the use of those tools.

Science is increasingly more present in our everyday decisions, with a fundamental role in global problems. Scientists, as the main actors in the production of scientific knowledge, have the responsibility of having an active voice in communicating this knowledge.

The course aims at introducing attendants to an updated state of the art of diversity of the soil biota and the functional roles played by soil organisms in key ecological processes.

Symbiosis is a key strategy for life on Earth. Nevertheless, although many research groups have long been committed to the study of symbiosis, its definition and functioning are not fully understood, and its ecological role and relevance are still underestimated.

This 5-day course offers to the participants a light microscopy course focusing on fluorescence microscopy techniques applied to the detection of proteins and glycans in tissue samples and cell cultures.

This course aims to explore ways of communicating science to non-specialized audiences, such as policy makers, industry, general public (including students and teachers), through their engagement and participation in citizen science activities.

A 19 de abril de 2023 celebra-se o 112.º aniversário da Faculdade de Ciências da Universidade de Lisboa.

The objective of this course is to provide students with basic knowledge of R programming, allowing them to manipulate and visualize data with R.

The objective of this course is to provide students with statistical knowledge and tools to manipulate, analyze and visualize biological data with R. Introduction to modeling, simulations and Bayesian statistics.

Under the general framework of Global Change Ecology, the goal of this course is to provide the participants with the most recent and practical knowledge on the use of Functional Diversity. This includes the selection of functional traits and calculation of Functional Diversity Indexes.
