This course provides a general introduction to computers as a problem-solving tool using the C programming language. Emphasis is on algorithms and techniques useful to engineers. Topics include data representation, debugging, and program verification. Some programming assignments may involve complex arithmetic and trigonometric and exponential functions. 4 credit hours

An Introduction to Voting Rule Verification

We give an introduction to deductive verification methods that can be used to formally prove that voting rules and their implementations satisfy specified properties and conform to the desired democratic principles. In the first part of the paper we explain the basic principles: We describe how first-order logic with theories can be used to formalise the desired properties. We explain the difference between (1) proving that one set of properties implies another property, (2) proving that a voting rule implementation has a certain property, and (3) proving that a voting rule implementation is a refinement of an executable specification. And we explain the different technologies: (1) SMT-based testing, (2) bounded program verification, (3) relational program verification, and (4) symmetry breaking. In this first part of the paper, we also explain the difference between verifying functional and relational properties (such as symmetries). In the second part, we present case studies, including (1) the specification and verification of semantic properties for an STV rule used for electing the board of trustees for a major international conference and (2) the deduction-based computation of election margins for the Danish national parliamentary elections

Program Model Checking: A Practitioner's Guide

Program model checking is a verification technology that uses state-space exploration to evaluate large numbers of potential program executions. Program model checking provides improved coverage over testing by systematically evaluating all possible test inputs and all possible interleavings of threads in a multithreaded system. Model-checking algorithms use several classes of optimizations to reduce the time and memory requirements for analysis, as well as heuristics for meaningful analysis of partial areas of the state space Our goal in this guidebook is to assemble, distill, and demonstrate emerging best practices for applying program model checking. We offer it as a starting point and introduction for those who want to apply model checking to software verification and validation. The guidebook will not discuss any specific tool in great detail, but we provide references for specific tools

Design and prototyping of real-time systems using CSP and CML

A procedure for systematic design of event based systems is introduced by means of the Production Cell case study. The design is documented by CSP-style processes, which allow both verification using formal techniques and also validation of a rapid prototype in the functionallanguage CML. 1. Introduction Notations like CSP [1] or CCS [2] provide concise notations for documenting the design of reactive or real-time systems. These notations further allow verification of properties through calculation, or model checking [3]. Yet there is a sizable gap from such specifications to executable programs needed to validate or test the design [4, 5, 6, 7]. In this paper we demonstrate how this gap is closed by CML [8], an extension of ML [9]. As shown in this paper, it is easy to get from a CSP design to an executable CML program, and the program can be interfaced to programs in other programming languages. We illustrate this idea by applying the design method for real-time systems presented in..

Formal Methods for the Verification of Safety Critical Applications using SPIN Model Checker

Security over the years has been a major concern for the organizations and companies.With the emergence of smart cards, industry has become more interested in methodologies which are used to establish the correctness and security of the applications developed with the acceptance of the use of smart cards in such domains.This paper provides a general introduction to the state-of-the-art of formal methods for the development of safety-critical systems. The idea is to combine two program verification approaches: the functional verification at the source code level and the verification of high level properties on a formal model built from the program and its specification. One of the important security systems in building security is door access control. The door access control is a physical security that assures the security of a building by limiting access to the building to specific people and by keeping records of such entries.In thispaper we employ a model checking method to verify the functional aspects of the smartcard operated door lock system which authenticates each person entering the building.PROMELA model for the proposed system Is presented.

Fly-by-light flight control system technology development plan

The results of a four-month, phased effort to develop a Fly-by-Light Technology Development Plan are documented. The technical shortfalls for each phase were identified and a development plan to bridge the technical gap was developed. The production configuration was defined for a 757-type airplane, but it is suggested that the demonstration flight be conducted on the NASA Transport Systems Research Vehicle. The modifications required and verification and validation issues are delineated in this report. A detailed schedule for the phased introduction of fly-by-light system components has been generated. It is concluded that a fiber-optics program would contribute significantly toward developing the required state of readiness that will make a fly-by-light control system not only cost effective but reliable without mitigating the weight and high-energy radio frequency related benefits
