James X. Owen isn't a people person. He was sent into what was to be a suicide mission to Chile. With the aid of an FBI lady named Susan Channing, the two of them escaped. The two are then given yet another assignment, what the FBI thinks is a suicide mission. They complete the mission, using Jim's ferocity and Susan's skill with guns, only to find themselves stranded in Mexico. Well, Jim had foreseen the problem and maybe his escape plan might work.

This book constitutes the refereed conference proceedings of the 20th International Conference on Principles and Practice of Constraint Programming, CP 2014, held in Lyon, France, in September 2014. The 65 revised papers presented together with 4 invited talks were carefully selected from 108 submissions. The scope of CP 2014 includes all aspects of computing with constraints, including theory, algorithms, environments, languages, models, systems, and applications such as decision making, resource allocation, and agreement technologies.

Designed for engineers, mathematicians, computer scientists, financial analysts, and anyone interested in using numerical linear algebra, matrix theory, and game theory concepts to maximize efficiency in solving applied problems. The book emphasizes the solution of various types of linear programming problems by using different types of software, but includes the necessary definitions and theorems to master theoretical aspects of the topics presented. Features: Emphasizes the solution of various types of linear programming problems by using different kinds of software, e.g., MS-Excel, solutions of LPPs by Mathematica, MATLAB, WinQSB, and LINDO Provides definitions, theorems, and procedures for solving problems and all cases related to various linear programming topics Includes numerous application examples and exercises, e.g., transportation, assignment, and maximization Presents numerous topics that can be used to solve problems involving systems of linear equations, matrices, vectors, game theory, simplex method, and more.

This is the second time that of ESOP has formed part of the ETAPS cluster of conferences, workshops, working group meetings and other associated activities. One of the results of colocatingso many conferences is a reduction in the number of possibilities to submit a paper to a European conference and the increased competition between conferences that occurs when boundaries between indiv- ual conferences have not yet become well established. This may have been the reason for the fact that only 44 submission were received this year. On the other hand we feel that the average quality of submissions has gone up, and thus the program committee was able to select 18 good papers, only one less than the year before. The program committee did not meet physically, and all discussion was done usinga Web-driven data base system. Despite some mixed feelings there is an overall tendency to appreciate the extra time available for giving papers a s- ond look and really going into comments made by other program committee members. I want to thank my fellow program committee members for the work they have put into the refereeingprocess and the valuable feedback they have given to authors. I want to thank the referees for their work and many detailed comments, and ?nally I want to thank everyone who has submitted a paper: without authors, no conference.
