. Cem Say is the author of the QSI algorithm for qualitative system identification, an AI task relevant in the study of qualitative reasoning. His work in complexity theory includes studies on small-space quantum automata and new characterizations of the complexity classes NL and P in terms of verifiers modeled by finite-state machines allowed to use only a fixed number of random bits. He is also known for his advocacy of people wrongly accused with forged digital evidence, and his popular science books.
