Welcome to COLA Laboratory #

Computational Optimization for Learning and Adaptive Systems (COLA) laboratory is working in computational/artificial intelligence, multi-objective optimization and decision-making, operational research, machine learning and statistical modeling of complex systems. Applications focus on search-based software engineering, energy, biological science and medicine.

We are constantly looking for talented and passionate people to join our lab. Please refer to vacancies for potential opportunities.
I have been working on the update of this website, though it has been a bit slow.
