This Microworld is the second half of a 12-week course in Discrete Mathematics. The term "Discrete Mathematics" in this Microworld will refer loosely to the collection of techniques, ideas, and constructions that have evolved over the years to describe artificial systems, and in particular, those systems from which the modern theories of computing have evolved. So, for example, an excellent model for our subject is the Turing Machine, or, equivalently, the lambda-calculus of Alonzo Church. In fact, the lambda-calculus is the conceptual basis for the computer language, LISP , which is the language in which this Microworld is written. We recommend that you follow the 9 readings of this Microworld in the order in which they appear below, beginning with "Iteration and Recursion."

Encyclopaedia of Mathematics R Article referred from Article refers to Recursive set theory A branch of the theory of recursive functions (cf. Recursive function ) that examines and classifies subsets of natural numbers from the point of view of algorithms, and also studies the structures arising as a result of such a classification. For each subset of the set of all natural numbers , the following decision problem can be formulated: Is there an algorithm that permits one to decide, for any , whether or not is a member of The mathematical posing of problems of this kind, and the development of recursive set theory, only became possible in the 's after the successful formalization of the intuitive concept of an (algorithmically) computable function . The range of values of such functions forms the family of recursively-enumerable sets (cf. also Enumerable set ). Sets for which the problem formulated above is solvable are called recursive. In fact, is recursive if and only if and are both recursively enumerable. The first examples of non-recursive recursively-enumerable sets turned out to be the so-called creative sets: a recursively-enumerable set is called creative (cf. also

20. Data Structures And Programming Lecture 1 Data types vs. Data structures. A data type is a welldefined collection of data of a set with such operations as intersection, union, and equivalence. http://www.cs.sunysb.edu/~skiena/214/lectures/lect1/lect1.html

Next: About this document Up: My Home Page Data Structures and Programming Lecture 1 Steven S. Skiena Why Data Structures? In my opinion, there are only three important ideas which must be mastered to write interesting programs. Iteration - Do, While, Repeat, If Data Representation - variables and pointers Subprograms and Recursion - modular design and abstraction At this point, I expect that you have mastered about 1.5 of these 3. It is the purpose of Computer Science II to finish the job. Data types vs. Data Structures A data type is a well-defined collection of data with a well-defined set of operations on it. A data structure is an actual implementation of a particular abstract data type. Example: The abstract data type Set has the operations EmptySet(S), Insert(x,S), Delete(x,S), Intersection(S1,S2), Union(S1,S2), MemberQ(x,S), EqualQ(S1,S2), SubsetQ(S1,S2). This semester, we will learn to implement such abstract data types by building data structures from arrays, linked lists, etc. Modula-3 Programming Control Structures: IF-THEN-ELSE, CASE-OF

Kakutani (Kyoto University, Japan) M. Hasegawa (Kyoto University, Japan) The lambda-mu-calculus features both variables and names, together with their binding mechanisms. This means that constructions on open terms are necessarily parameterized in two different ways for both variables and names. Semantically, such a construction must be modeled by a bi-parameterized family of operators. In this paper, we study these bi-parameterized operators on Selinger's categorical models of the lambda-mu-calculus called control categories. The overall development is analogous to that of Lambek's functional completeness of cartesian closed categories via polynomial categories. As a particular and important case, we study parameterizations of uniform fixed-point operators on control categories, and show bijective correspondences between parameterized fixed-point operators and non-parameterized ones under uniformity conditions.

International Presented at the 17-th EuroForth Conference (23-26 November 2001, Schloss Dagstuhl, Saarbruecken, Germany) by Reuben Thomas, on my behalf and with my thanks. Synopsis of the language Joy This paper is intended as an introduction for Forth programmers. Introduction To add two integers, say 2 and 3, and to write their sum, you type the program This is how it works internally: the first numeral causes the integer 2 to be pushed onto a stack. The second numeral causes the integer 3 to be pushed on top of that. Then the addition operator pops the two integers off the stack and pushes their sum, 5. So the notation looks like ordinary postfix. The Joy processor reads programs like the above until they are terminated by a period. Only then are they executed. In the default mode the item on the top of the stack (5 in the example) is then written to the output file, which normally is the screen. To compute the square of an integer, it has to be multiplied by itself. To compute the square of the sum of two integers, the sum has to be multiplied by itself. Preferably this should be done without computing the sum twice. The following is a program to compute the square of the sum of 2 and 3:

VHDL Sign-off Simulation : What Future? A VHDL-based System-Design Methodology Gajski, Daniel D; Abstract As methodologies and tools for chip-level design mature, design effort becomes focused on increasingly higher levels of abstraction. We present a methodology and tool for system-level specification, design and refinement, based on VHDL, that results in an executable specification for each system component. The specification for each component can then be synthesized into hardware or compiled to software. We highlight advantages of the proposed methodology compared to current practice.

BACK TO LIST An Automatic Test Bench Generation System Kapoor, Shekhar; Armstrong, James R; Rao, Sanat R; Abstract This paper presents an automatic test bench generation system for VHDL behavioral models. Modeler's Assistant, an interactive CAD tool developed at Virginia Tech, gives the graphical representation of a VHDL behavioral model, called a Process Model Graph (PMG). The Process Test Generator (PTG) is used to generate the stimulus/response test sets for individual processes of a PMG. The Hierarchical Behavioral Test Generator (HBTG) accepts the PMG and the test sets produced by PTG as inputs, and then hierarchically constructs a test sequence for the entire model. The test sequence is converted into a test bench by the Test Bench Generator (TBG), and it is then used for simulation of the model. Experimental results show that the test benches generated exercise the models thoroughly.

Abstracts The topos of 3-colored graphs The problem of 3 coloring finite undirected graphs is NP-complete and therefore there is interest in the structure of graphs which are and are not 3 colorable. The category of undirected graphs U is a topos. A graph with a given 3 coloring is said to be 3-colored. The category C of 3-colored graphs is is a cocomplete topos, hence also complete. There is an essential geometric morphism between U and C, and the three functors involved have considerable natural appeal. These functors justify two of the heuristics used to quicken algorithms which determine whether or not a 3 coloring exists for argument finite undirected graphs. Indeed, one of these heuristics deserves to be better known. ... Finally, we observe that instead of B we might take any pca of the form L/T where T is a theory containing the (obvious) conversion theory for L and itself being containEd in Th(A). This may be considered as a solution of (a variant of) the Longley-Phoa Conjecture claiming that realisability over a term model of untyped lambda-calculus gives rise to a fully abstract model of PCF.

Given any such f M , we construct a real-time deterministic pushdown automata (DPDA) that recognizes the complete plays of the knowing-strategy denotation of M . Since such plays characterize observational equivalence, and there is an algorithm for deciding whether any two DPDAs recognize the same language, we obtain a procedure for deciding observational equivalence of 3rd-order finitary IA. This algorithmic representation of program meanings, which is compositional, provides a foundation for model-checking a wide range of behavioural properties of IA and other cognate programming languages. Another result concerns 2nd-order IA with full recursion: we show that observational equivalence for this fragment is undecidable. Martin Hyland, U Cambridge, UK

Data Structures / Algebraic Semantics ~ Under Construction ~ Product Type Constructor Natural Numbers Stack[Item] List[Item] ... Directed Graph Overview An ontology that claims to represent data structures should be able to model the axiomatic semantics of the commonly occurring data structures, such as stacks, arrays, queues, binary trees, trees, s-expressions, nested lists, directed graphs, etc. Most data structure types have three classes of operations: constructors, accessors and tests. When suitably expressive, data structure types should allow for the recursive definitions of functions. New Tags and Attributes For greater convenience in data structuring and algebraic semantics, we have included src and tgt referencing attributes, in addition to the previous obj referencing attribute, and we have extended the Function element to include a free-standing version. With the src and tgt attributes we can embed functions in object specifications when the ambient object is either the source or target of the function. Most container classes have a parameter type, which is the type of the contained items. In order to accomodate this, a

The mathematics of sentence structure JOACHIM LAMBEK The definitions [of the parts of speech] are very far from having attained the degree of exactitude found in Euclidean geometry Otto Jespersen ( Contents Introduction Syntactic types Type list for a fragment of English Formal systems ... REFERENCES 1. Introduction The aim of this paper is to obtain an effective rule (or algorithm) for distinguishing sentences from nonsentences, which works not only for the formal languages of interest to the mathematical logician, but also for natural languages such as English, or at least for fragments of such languages. An attempt to formulate such an algorithm is implicit in the work of Ajdukiewicz ( . His method, later elaborated by Bar-Hillel ( ), depends on a kind of arithmetization of the so-called parts of speech , here called syntactic types The present paper begins with a new exposition of the theory of syntactic types. It is addressed to mathematicians with at most an amateur interest in linguistics. The choice of sample languages is therefore restricted to English and mathematical logic. For the same reason, technical terms have been borrowed from the field of high school grammar. Only a fragmentary treatment of English grammar is presented here. This should not be taken too seriously, but is meant to provide familiar illustrations for our general methods. The reader should not be surprised if he discovers considerable leakage across the line dividing sentences from nonsentences. It is only fair to warn him that some authorities think that such difficulties are inherent in the present methods

41. A Neighborhood Of Infinity: Data And Codata It allows so much fun variation in the structure of Recursive types. Are these ideas equivalent to recursion and corecursion, or is the similarity just http://sigfpe.blogspot.com/2007/07/data-and-codata.html

A Neighborhood of Infinity Saturday, July 14, 2007 Data and Codata In , Hofstadter introduces the programming language Bloop . Bloop is a little like BASIC except that it forces programmers to specify in advance how many times each loop will iterate. As a result, Bloop programs have the handy property that they are guaranteed to terminate. Unfortunately this property also makes it impossible to write something like an operating system in Bloop. To write an OS we need open-ended loops that keep running until the user explicitly chooses to shut the OS down. One solution to this is to write code in Floop . Floop allows us to write unbounded loops, the equivalent of C's . The problem with that, however, is that we can write runaway infinite loops that never terminate and never give us any output. Is there some language that lies between Bloop and Floop that can give us unbounded looping when we need it, but which never allows us to hoist ourselves by our petards by writing runaway loops? Wishing no disrepsect to OS writers, at first blush it might seem that the distinction between a runaway loop and an idle OS is too fine - if we can write an infinite loop that does something useful, then surely we can write a useless one too. But it turns out that there is a very elegant and well-principled way to distinguish between these kinds of loops, and this allows us to write open-ended interactive software in a programming language that nonetheless always produces a well-defined output, no matter what the input. In order to do this we need to distinguish between two kinds of data:

Data structures and languages for RAM are core computer science. The Aldat Project is concerned with language and data structures for SS. Secondary storage is distinguished from RAM primarily by the long times required to find data, relative to the times required to transfer it for processing. Different memory organization needs different data structures, algorithms and languages. There are many general-purpose languages for RAM and it is unusual to encounter languages specialized for individual applications. Languages for SS are usually query languages rather than full programming languages, and they are specialized both to particular data structures (hierarchies, linked lists, tables, etc.) and to particular applications (administrative data, spatio-temporal data, logic data, semistructured data, etc.) For instance, RAM has no spatio-temporal dialect of FORTRAN or Java, but SS has Arc-Info while commercial relational databases (SS) do not have comparable spatial capability except as add-ons. Aldat is a general purpose SS programming language developed at McGill University . This development has been empirical, following and sometimes leading the main thrusts of database research (including hierarchies, data-structure-set, multiset relations, entities and relationships, object-oriented databases, logic databases, active databases, data warehousing, data mining, semistructured data, and Internet data) with the aim of including all the evolving possibilities of SS programming. The difficulties of doing this are captured in the phrase "impedance mismatch", which characterizes the gaps among applications on one hand and between querying and programming on the other.

FIRST SEMESTER MODEL THEORY (Wim Veldman) In mathematics one often studies the class of structures satisfying a given set of formal axioms, for instance the class of groups, the class of fields, or the class of linear orders. In Model Theory one starts to study the rather general case that the axioms are formulated in a first-order or elementary language. This means that, when interpreting the formulas of such a language, one only quantifies over the domain of the structure, and not, for instance, over the power set of the domain. The pivotal notion of model theory is the notion of a formula being true in a mathematical structure. This notion has been given a formal definition by A. Tarski. Axiomatizing a structure is closely related to finding a method to decide which sentences are true in the structure. We shall discuss Tarski's quantifier elimination results. Given a formal theory, what can we say about the class of its countable models? We give a characterization, due to several mathematicians independently, of theories that have exactly one countable model.

53. Induction, Recursion, Replacement And The Ordinals the equivalence between my notion of wellfoundedness (induction) and the recursion scheme due to Osius, for endofunctors of Set that preserve inverse http://www.monad.me.uk/ordinals/

Induction, recursion, replacement and the ordinals Paul Taylor My chief contribution to this subject is the notion of " well founded coalgebra ", which is described briefly in the "extended abstract" below and also Sections and of my book, Practical Foundations of Mathematics . The detailed treatment is in the full paper that is the second item below. In particular, this proves the equivalence between my notion of well-foundedness (induction) and the recursion scheme due to Osius, for endofunctors of Set that preserve inverse images, that, if the functor has an initial algebra, a coalgebra for it is well founded iff it has a coalgebra homomorphism to the initial algebra, and that extensional well founded coalgebras behave in many ways like sets (of the set-theoretic kind), in particular their coproducts "overlap" in a similar way, and are idempotent like joins in a lattice. Parametric recursion is covered in the Exercises for Chapter VI of the book. The earlier JSL paper on Intutionistic Sets and Ordinals treats them in the normal without replacement.
