On the algebraic structure of combinatorial problems - LIX
We describe a general algebraic formulation for a wide range of combinatorial problems including SATISFIABILITY, GRAPH COLORABILITY and GRAPH ISOMORPHISM.
Counting Graph Homomorphisms(c) Partition functions of many models in statistical mechanics can be expressed as graph homomorphism functions. For example, let G be an n × n grid, and ... Mathématique - Comptes Rendus de l'Académie des SciencesTherefore if our family of d-reguler graphs (Gn) satisfies BST, then the Benjamini?Schramm limit of (Gn ?C4) is Td ?C4. Examining the entries of the Green's ... Linear Least-Squares Algorithms for Temporal Difference LearningWe introduce two new TD algorithms based on the theory of linear least-squares function approximation. The recursive least-squares function approxima- tion ...
