The future development of complexity theory will require a subtle understanding of the similarities, differences and limitations of the many current approaches. In fact, even though these approaches study the same phenomenon, they are developed today within disjoint communities, with little or no communication between them (e.g. algorithms, logic, programming theory, algebra etc.). This dispersion is unfortunate since it hinders the development of hybrid methods and more generally the advancement of computational complexity as a whole.
The EPIT 2023 (École de printemps d'informatique théorique), which marked the 50th edition of this series of research schools, reunited in a single event as many different takes on computational complexity as can reasonably be fit in one week. It was intended for Ph.D. students as well as established researchers who wish to learn more about neighboring areas.
