TÍTULO: "Optimization for simulation based problems"

RESUMEN: The need of frugal products, services with high quality and resilience, or more generally new efficient systems can take the avantage of using digital twin during the design phase. A digital twin which is a numerical model allows to try, and test new potential designs among thousands with a reduced cost, and higher safety. Then, black-box optimization techniques such as local searches or evolutionary algorithms, can be used to find efficient new design by simulating the digit twin. In this case, one of the main difficulty is the computation time of the simulation which can be high. This talk will give two examples of simulation based problems, and different approaches to solve them. In particular, surrogate model approach will be present which learn a model of the simulation in order to accelerate the search throw the optimization search space.
