  • Various feature descriptions are being employed in constrained-based grammar formalisms. The common notational primitive of these descriptions are functional attributes called features. The descriptions considered in this paper are the possibly quantified first-order formulae obtained from a signature of features and sorts. We establish a complete firstorder theory F T by means of three axiom schemes and construct three elementarily equivalent models. One of the models consists of so-called feature graphs, a data structure common in computational linguistics. ...

  • A purely functional implementation of LR-parsers is given, together with a simple correctness proof. It is presented as a generalization of the recursive descent parser. For non-LR grammars the time-complexity of our parser is cubic if the functions that constitute the parser are implemented as memo-functions, i.e. functions that memorize the results of previous invocations. Memo-functions also facilitate a simple way to construct a very compact representation of the parse forest.

  • This module begins an in-depth discussion of the function. Functions are the building blocks of C++, and a firm understanding of them is fundamental to becoming a successful C++ programmer. Here, you will learn how to create a function. You will also learn about passing arguments, returning values, local and global variables, function prototypes, and recursion.

  • If you want to learn how to program, working with Python is an excellent way to start. This hands-on guide takes you through the language one step at a time, beginning with basic programming concepts before moving on to functions, recursion, data structures, and object-oriented design. Through exercises in each chapter, you’ll try out programming concepts as you learn them. Think Python is ideal for students at the high school or college level, as well as self-learners, home-schooled students, and professionals who need to learn programming basics....

  • A respectable period of time has passed since the first edition of this book, during which several pressures have necessitated a second edition. Most important, there were the inadvertent errors needing correction. The field has also had some significant changes, not so much in methodology perhaps as in context, regulation, and the like. I can say some things more clearly now than previously because many issues are better defined or I care more (or less) about how the discussion will be received....

  • This paper proposes a simple consumption-based explanation of both the cross-sectional variation in expected stock returns and the countercyclical vari- ation in the equity premium. I use a representative household model, in which intraperiod utility is a constant elasticity of substitution (CES) function of nondurable and durable consumption. The household’s intertemporal utility is Epstein and Zin’s (1991) recursive function, which allows for the separation of the elasticity of intertemporal substitution (EIS) from risk aversion.
