Programming in Prolog

1.- Gives the student a "feel" for what it is like to program in Prolog. Introduces objects, relationships, facts, rules, variables..- 1.1 Facts.- 1.2 Questions.- 1.3 Variables.- 1.4 Conjunctions.- 1.5 Rules.- 1.6 Summary and Exercises.- 2.- More detailed presentation of Prolog syntax and data structures..- 2.1 Syntax.- 2.2 Characters.- 2.3 Operators.- 2.4 Equality and Matching.- 2.5 Arithmetic.- 2.6 Summary of Satisfying Goals.- 3.- Representing objects and relationships by using "trees" and "lists". Developing several standard Prolog programming techniques..- 3.1 Structures and Trees.- 3.2 Lists.- 3.3 Recursive Search.- 3.4 Mapping.- 3.5 Recursive Comparison.- 3.6 Joining Structures Together.- 3.7 Accumulators.- 3.8 Difference Structures.- 4.- How a set of clauses generates a set of solutions. Using "cut" to modify the control sequence of running Prolog programs..- 4.1 Generating Multiple Solutions.- 4.2 The "Cut".- 4.3 Common Uses of the Cut.- 4.4 Problems with the Cut.- 5.- Facilities available for the input and output of characters and structures. Developing a program to read sentences from the user and represent the sentence as a list of words, which can be used with the Grammar Rules of Chapter 9..- 5.1 Reading and Writing Terms.- 5.2 Reading and Writing Characters.- 5.3 Reading English Sentences.- 5.4 Reading and Writing Files.- 5.5 Declaring Operators.- 6.- Definition of the "core" built-in predicates, with sensible examples of how each one is used. By this point, the reader should be able to read reasonably complex programs, and should therefore be able to absorb the built-in predicates by seeing them in use..- 6.1 Entering New Clauses.- 6.2 Success and Failure.- 6.3 Classifying Terms.- 6.4 Treating Clauses as Terms.- 6.5 Constructingand Accessing Components of Structures.- 6.6 Affecting Backtracking.- 6.7 Constructing Compound Goals.- 6.8 Equality.- 6.9 Input and Output.- 6.10 Handling Files.- 6.11 Evaluating Arithmetic Expressions.- 6.12 Comparing Numbers.- 6.13 Watching Prolog at Work.- 7.- Many example programs are given, covering a wide range of interests. New examples include list processing, set operations, symbolic differentiation and simplification of formulae..- 7.1 A Sorted Tree Dictionary.- 7.2 Searching a Maze.- 7.3 The Towers of Hanoi.- 7.4 Parts Inventory.- 7.5 List Processing.- 7.6 Representing and Manipulating Sets.- 7.7 Sorting.- 7.8 Using the Database: random, gensym, findall.- 7.9 Searching Graphs.- 7.10 Sift the Two's and Sift the Three's.- 7.11 Symbolic Differentiation.- 7.12 Mapping Structures and Transforming Trees.- 7.13 Manipulating Programs.- 8.- By this point, the reader will be able to write reasonable programs, and so the problem of debugging will be relevant. Flow of control model, hints about common bugs, techniques of debugging..- 8.1 Laying out Programs.- 8.2 Common Errors.- 8.3 The Tracing Model.- 8.4 Tracing and Spy Points.- 8.5 Fixing Bugs.- 9.- Applications of existing techniques. Using Grammar Rules. Examining the design decisions for some aspects of analysing natural language with Grammar R ules..- 9.1 The Parsing Problem.- 9.2 Representing the Parsing Problem in Prolog.- 9.3 The Grammar Rule Notation.- 9.4 Adding Extra Arguments.- 9.5 Adding Extra Tests.- 9.6 Summary.- 10.- Predicate Calculus, clausal form, resolution theorem proving, logic programming..- 10.1 Brief Introduction to Predicate Calculus.- 10.2 Clausal Form.- 10.3 A Notation for Clauses.- 10.4 Resolution and Proving Theorems.- 10.5 Horn Clauses.- 10.6 Prolog.- 10.7 Prolog and LogicProgramming.- 11.- A selection of suggested exercises, projects, and problems..- 11.1 Easier Projects.- 11.2 Advanced Projects.- Appendices.- A. Answers to Selected Exercises.- B. Clausal Form Program Listings.- C. Different Versions of Prolog.- D. Edinburgh Prolog.- E. micro-Prolog.
