"Dissection: A New Paradigm for Solving Bicomposite Search Problems," by Itai Dinur, Orr Dunkelman, Nathan Keller, and Adi Shamir, presents an elegant new algorithm for solving a broad class of combinatorial optimization problems…
In this paper, we introduce the new notion of bicomposite search problems, and show that they can be solved with improved combinations of time and space complexities by using a new algorithmic paradigm called dissection.
