Well-Founded Functions and Extreme Predicates in Dafny: a Tutorial
EPiC Series in Computing Volume 40, 2016, Pages 52–66 IWIL-2015. 11th International Work- shop on the Implementation of Logics Well-founded Functions and Extreme Predicates in Dafny: A Tutorial K. Rustan M. Leino Microsoft Research [email protected] Abstract A recursive function is well defined if its every recursive call corresponds a decrease in some well-founded order. Such well-founded functions are useful for example in computer programs when computing a value from some input. A boolean function can also be defined as an extreme solution to a recurrence relation, that is, as a least or greatest fixpoint of some functor. Such extreme predicates are useful for example in logic when encoding a set of inductive or coinductive inference rules. The verification-aware programming language Dafny supports both well-founded functions and extreme predicates. This tutorial describes the difference in general terms, and then describes novel syntactic support in Dafny for defining and proving lemmas with extreme predicates. Various examples and considerations are given. Although Dafny’s verifier has at its core a first-order SMT solver, Dafny’s logical encoding makes it possible to reason about fixpoints in an automated way. 0. Introduction Recursive functions are a core part of computer science and mathematics. Roughly speaking, when the definition of such a function spells out a terminating computation from given arguments, we may refer to it as a well-founded function. For example, the common factorial and Fibonacci functions are well-founded functions. There are also other ways to define functions. An important case regards the definition of a boolean function as an extreme solution (that is, a least or greatest solution) to some equation. -

Programming Language Features for Refinement
Programming Language Features for Refinement Jason Koenig K. Rustan M. Leino Stanford University Microsoft Research [email protected] [email protected] Algorithmic and data refinement are well studied topics that provide a mathematically rigorous ap- proach to gradually introducing details in the implementation of software. Program refinements are performed in the context of some programming language, but mainstream languages lack features for recording the sequence of refinement steps in the program text. To experiment with the combination of refinement, automated verification, and language design, refinement features have been added to the verification-aware programming language Dafny. This paper describes those features and reflects on some initial usage thereof. 0. Introduction Two major problems faced by software engineers are the development of software and the maintenance of software. In addition to fixing bugs, maintenance involves adapting the software to new or previously underappreciated scenarios, for example, using new APIs, supporting new hardware, or improving the performance. Software version control systems track the history of software changes, but older versions typically do not play any significant role in understanding or evolving the software further. For exam- ple, when a simple but inefficient data structure is replaced by a more efficient one, the program edits are destructive. Consequently, understanding the new code may be significantly more difficult than un- derstanding the initial version, because the source code will only show how the more complicated data structure is used. The initial development of the software may proceed in a similar way, whereby a software engi- neer first implements the basic functionality and then extends it with additional functionality or more advanced behaviors. -
Developing Verified Sequential Programs with Event-B
UNIVERSITY OF SOUTHAMPTON Developing Verified Sequential Programs with Event-B by Mohammadsadegh Dalvandi A thesis submitted in partial fulfillment for the degree of Doctor of Philosophy in the Faculty of Physical Sciences and Engineering Electronics and Computer Science April 2018 UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF PHYSICAL SCIENCES AND ENGINEERING ELECTRONICS AND COMPUTER SCIENCE Doctor of Philosophy by Mohammadsadegh Dalvandi The constructive approach to software correctness aims at formal modelling of the in- tended behaviour and structure of a system in different levels of abstraction and verifying properties of models. The target of analytical approach is to verify properties of the final program code. A high level look at these two approaches suggests that the con- structive and analytical approaches should complement each other well. The aim of this thesis is to build a link between Event-B (constructive approach) and Dafny (analytical approach) for developing sequential verified programs. The first contribution of this the- sis is a tool supported method for transforming Event-B models to simple Dafny code contracts (in the form of method pre- and post-conditions). Transformation of Event-B formal models to Dafny method declarations and code contracts is enabled by a set of transformation rules. Using this set of transformation rules, one can generate code contracts from Event-B models but not implementations. The generated code contracts must be seen as an interface that can be implemented. If there is an implementation that satisfies the generated contracts then it is considered to be a correct implementation of the abstract Event-B model. A tool for automatic transformation of Event-B models to simple Dafny code contracts is presented. -

It targets the C# language and is a .NET Roslyn live analyzer providing live analysis feedback to the developers using it. ReDi uses principles from formal specification and symbolic execution to implement methods for performing domain restriction on variables, parameters, and return values. A domain restriction is an invariant implemented as a check function, that can be applied to variables utilizing an annotation referring to the check method. ReDi can also help to prevent runtime exceptions caused by null pointers. ReDi can prevent null exceptions by integrating nullability into the domain of the variables, making it feasible for ReDi to statically keep track of null, and de- tecting variables that may be null when used. ReDi shows promising results with finding inconsistencies and faults in some programming projects, the open source CoreWiki project by Jeff Fritz and several web service API projects for services offered by Innovation Norway. -

Dafny: an Automatic Program Verifier for Functional Correctness K
Dafny: An Automatic Program Verifier for Functional Correctness K. Rustan M. Leino Microsoft Research [email protected] Abstract Traditionally, the full verification of a program’s functional correctness has been obtained with pen and paper or with interactive proof assistants, whereas only reduced verification tasks, such as ex- tended static checking, have enjoyed the automation offered by satisfiability-modulo-theories (SMT) solvers. More recently, powerful SMT solvers and well-designed program verifiers are starting to break that tradition, thus reducing the effort involved in doing full verification. This paper gives a tour of the language and verifier Dafny, which has been used to verify the functional correctness of a number of challenging pointer-based programs. The paper describes the features incorporated in Dafny, illustrating their use by small examples and giving a taste of how they are coded for an SMT solver. As a larger case study, the paper shows the full functional specification of the Schorr-Waite algorithm in Dafny. 0 Introduction Applications of program verification technology fall into a spectrum of assurance levels, at one extreme proving that the program lives up to its functional specification (e.g., [8, 23, 28]), at the other extreme just finding some likely bugs (e.g., [19, 24]). Traditionally, program verifiers at the high end of the spectrum have used interactive proof assistants, which require the user to have a high degree of prover expertise, invoking tactics or guiding the tool through its various symbolic manipulations. Because they limit which program properties they reason about, tools at the low end of the spectrum have been able to take advantage of satisfiability-modulo-theories (SMT) solvers, which offer some fixed set of automatic decision procedures [18, 5]. -
Quick Notes on Nodexl
Quick notes on NodeXL Programme organisation, 3 components: • NodeXL command ‘ribbon’ – access with menu-like item at top of the screen, contains all network data functions • Data sheets – 5 separate sheets for edges, vertices, metrics etc, switching between them using tabs on the bottom. NB because the screen gets quite crowded the sheet titles sometimes disappear off to one side so use the small arrows (bottom left) to scroll across the tabs if something seems to have gone missing. • Graph viewer – separate window pane labelled ‘Document Actions’ with graphical layout functions. Can be closed while working with data – to open it again click the ‘Show Graph’ button near the left-hand side of the ribbon. Working with data, basic process: 1. Start in ‘Edges’ data sheet (leftmost tab at the bottom); each row represents one connection of the form A links to B (directed graph) OR A and B are linked (undirected). (Directed/Undirected changed in ‘Type’ option on ribbon. In directed graph this sheet might include one row for A->B and one for B->A; in an undirected graph this would be tautologous.) No other data in this sheet is required, although optionally: • Could include text under ‘label’ if the visible label on graphs should be different from the name used in columns A or B. NB These might be overwritten when using ‘autofill columns’. • Could add an extra column at column L to identify weight of links if (as is the case with IssueCrawler data) each connection might represent more than 1 actually existing link between two vertices, hence inclusion of ‘Edge Weight’ in blogs data. -

NODEXL for Beginners Nasri Messarra, 2013‐2014
NODEXL for Beginners Nasri Messarra, 2013‐2014 http://nasri.messarra.com Why do we study social networks? Definition from: http://en.wikipedia.org/wiki/Social_network: A social network is a social structure made up of a set of social actors (such as individuals or organizations) and a set of the dyadic ties between these actors. Social networks and the analysis of them is an inherently interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory. From http://en.wikipedia.org/wiki/Sociometry: "Sociometric explorations reveal the hidden structures that give a group its form: the alliances, the subgroups, the hidden beliefs, the forbidden agendas, the ideological agreements, the ‘stars’ of the show". In social networks (like Facebook and Twitter), sociometry can help us understand the diffusion of information and how word‐of‐mouth works (virality).
