Chapter 5 On the First SAT / CP Integration Workshop

SAT and CP techniques are two problem solving technologies which share many similarities, and there is considerable interest in cross-fertilizing these two areas. The techniques used in SAT (propagation, activity-based heuristics, conflict analysis, restarts, etc.) constitute a very successful combination which makes modern DPLL solvers robust enough to solve large real-life instances without t...

Chapter I. First Variations

In abstract terms, the Calculus of Variations is a subject concerned with max/min problems for a real-valued function of several variables. Given a vector space V and a function Φ:V → R, we explore the theory and practice of minimizing Φ[x] over x ∈ V . Additional interest and power comes from allowing • dim(V ) = +∞, • constrained minimization, where the choice variable x must lie in some prea...

Chapter 12 FIRST - ORDER POLYNOMIAL

This chapter focuses on rst-order polynomial based theorem proving. We present the notion of well-behaved inference rules and two concrete such inference rules termed superposition I and superposition II. The SOS-strategy and the L-strategy for well-behaved inference rules are developed, and both of them are proved to be complete. We introduce the LM-strategy, the connuent LM-strategy, the MM-s...

CHAPTER 19 Internet - Based Virtual Environments

Hosting virtual worlds on the Internet introduces many problems not inherent in private networks. These include security, reliability, speed and differing agendas of participants. The purpose of this chapter is to review the history and present status of Internet-based virtual environments, and to discuss a number of efforts designed to meet perceived future needs. 1 Internet Protocols 1.1 The ...
