Optimization algorithms, artificial intelligence & robotics (AI)

Prototype of one of the robots of the robotic choral

This research pole deals with optimization algorithms, evolutionary computing, artificial intelligence and robotics.

Our goal is to develop evolutionary algorithms to address medium to large-scale computationally expensive optimization problems. These algorithms are based on natural selection strategies and take advantage of the computational resources of high-performance computing systems.

We also develop machine-learning algorithms for the analysis, classification or visualization of high-dimensional data. An objective is to achieve a better understanding of the roots of their functioning. We adopt here an interdisciplinary approach by enforcing the cross fertilisation among the involved disciplines.

We also carry out research activity in the domain of Evolutionary and Swarm Robotics. We have a lab equipped with Kilobots, E-pucks and other robotic platforms (https://www.naxys.be/robotics). We use evolutionary computation techniques as well as other bio-inspired control design algorithms to the synthesis of neurocontrollers for robots required to cooperate to execute tasks that are beyond the capabilities of single agents.
