Coffee break at DISI: stories of those researching AI outside Italian borders
The Department of Information Engineering and Computer Science (DISI) of the University of Trento became, for five days, the center of gravity for a global scientific community. Beyond the institutional dimension, the event highlighted a sociological dynamic relevant to the high-tech job market: the mobility of Italian talent.
During networking sessions, profiles emerge of Italian researchers who, while maintaining a link with Italy, have chosen to develop their careers in foreign research centers. Among them, Giorgia Nadizar, currently active at the University of Toulouse Capitole in France, and Elena Raponi. These testimonies highlight a trend of brain drain or, from a more strategic perspective, a circulation of skills that Italy must know how to intercept to avoid losing competitiveness in the AI sector.
Strategic analysis: For the Italian entrepreneur, this data suggests that the acquisition of AI talent cannot be limited to the domestic market, but must include attraction strategies for Italian researchers abroad, leveraging the attractiveness of centers of excellence such as the one in Trentino.

From neuroevolution to quantum optimization: the 17 thematic areas of PPSN 2026
The conference is not a monolith, but is articulated into 17 frontier thematic areas. This multidisciplinarity is fundamental for the application of AI in complex industrial contexts.
- LLM and Evolutionary Computation Integration: Research on how Large Language Models can be optimized via evolutionary algorithms to overcome the limits of traditional training.
- Quantum Optimization: Application of quantum mechanics principles to solve complex combinatorial optimization problems.
- Neuroevolution: Study of algorithms that evolve the architectures of neural networks themselves, rather than limiting themselves to optimizing weights.
- Reinforcement Learning: Development of agents capable of learning by trial and error in dynamic environments.
- Robotic Applications: Implementation of bio-inspired systems to improve the autonomy and adaptability of robots.
- Hybrid AI: Combination of different computing paradigms to obtain more robust and interpretable systems.
Business analysis: The focus on quantum optimization and neuroevolution suggests that the industry is preparing for a post-LLM phase, where computational efficiency and real-time adaptability will be the true competitive differentiators.
Beyond Large Language Models: how evolutionary computation is transforming robotics
Question: Why is evolutionary computation relevant if we already have LLMs?
Answer: While LLMs excel in language generation and textual data processing, evolutionary computation focuses on solving optimization problems inspired by nature. In robotics, this means creating systems that do not just follow pre-programmed instructions, but that evolve the best solution for a physical task, improving movement efficiency and interaction with the environment.
Question: What is the advantage of the hybrid AI mentioned in the conference?
Answer: Hybrid AI combines the processing power of traditional models with the flexibility of bio-inspired systems. This allows for overcoming the rigidity limits of purely statistical models, making AI more capable of handling the unexpected, an essential requirement for advanced industrial automation.
