Ng Kong Beng Public Lecture Series
About the Talk:
Wouldn’t it be nice if one could simply state a theorem that you don’t know how to prove, and then have a computer do all the work? Of course, this is impossible in general, but decision procedures do exist for some small domains. Combinatorics on words is one such domain. In this talk I will describe how automata play a crucial role in designing a theorem-prover called “Walnut”, and the wide variety of results one can prove with it. Dozens of results published in the literature can be reproved in seconds with almost no effort, and two incorrect results in the literature were corrected. In addition, Walnut can be used to prove many new results.
