Juris Hartmanis: The Beginnings of Computational Complexity,areer.. This is a very appropriate tribute since complexity theory is now approximately 25 years old and Juris has been a prime mover in the field throughout its history. I was privileged to have worked with Hartmanis during the early period of his complexity research, and I am grateful for this oppneedle 发表于 2025-3-25 18:32:26

Describing Graphs: A First-Order Approach to Graph Canonization, unordered graphs?” We consider the languages .. consisting of first-order logic restricted to . variables and .. consisting of .. plus “counting quantifiers”. We give efficient canonization algorithms for graphs characterized by .. or ... It follows from known results that all trees and almost all向下 发表于 2025-3-26 08:00:33

The Structure of Complete Degrees,s as diverse as combinatorics, logic, and operations research turn out to be NP-complete and thus computationally equivalent in the sense discussed in the next paragraph. PSPACE-completeness, NEXP-completeness, and completeness for other complexity classes have likewise been used to show commonalitiGEAR 发表于 2025-3-26 16:29:35
