Research Topics at the first glance

Computational Intelligence Optimization

When the problem cannot be solved by means of an exact method due to the lack of differentiability or even analytic expression an alternative way must be found

of Uncertainties

– Large Scale and Computationally Expensive Optimization Problems

Current Research Lines

Distributed Memetic/Evolutionary Algorithms

Compact Memetic/Evolutionary Algorithms

Distributed Algorithms• If a population is properly structured,

with no additional overhead, the performance might be significantly improved and thus highly dimensional problems (1000 D) can be handled.

Compact Algorithms

– belong to the class of Estimation Distribution Algorithms

– do not use a population of individuals– make use of a statistic representation of the

populationThis approach is necessary to solve complex optimization problems despite the absence of a full performance computer

Performances depend on the control system tuning.

Application Example

•A cartesian robot controller for pick&place

•Compact algorithm to optimize the nonlinear controller (NN)

•The system has been optimized in orderto reject the unpredictable payload variation

•No external computer has been used
