Commemorative Issue for Alan L. Seman
Alan L. Selman, a long-time editor and the Editor-in-Chief for 18 years, passed away on 22nd January 2021. Alan was a leader in computational complexity. He introduced various important research topics, including p-selective sets, natural self-reducible sets, promise problems, reducing search to decision problems, comparison of resource-bounded reducibilities, and multivalued nondeterministic functions. Alan also had done pioneering work in many areas of computational complexity theory, including sparse sets, relativization, average-case complexity, hierarchy theorems, structures of complete sets, and the complexity of multivalued functions.
In this special issue, we celebrate Alan’s life and commemorate his extraordinary contributions to the ﬁeld. The topics of interest include but are not limited to:
- average-case complexity
- circuit complexity
- comparison of reducibilities
- complexity theoretic characterizations of models
- function complexity
- hierarchy theorems
- parameterized complexity
- promise problems and disjoint NP-pairs
- public-key cryptography
- semi-feasible algorithms
- sparse sets
- structure of complete sets
We solicit contributions in the form of new research investigations, technical surveys, and memoirs. A technical contribution may include a section describing Alan’s inﬂuence on the authors, both on their academic careers and personal lives.
