After reading this, you can contact me any time to have an insightful discussion on the semantic differences between functional and declarative languages. It's semantics are strong enough that we can do reasoning from it. May 21, 2011 - The dominant theme in all three seminars was the gap between syntax and semantics, conceived as site for conceptual and mathematical invention rather than as a call to mimicry. The functional approach brings indeed several improvements over regular imperative or object-oriented programming. It is still composed of many discrete simple steps that excruciatingly calculate the output. Systems) and programmes (in the lambda calculus, the Turing machine formalism, or any actual computer), and so on, to linear logic, looking at the subtle tensions which emerge in our understanding of logic as we direct our attention to its hidden symmetries, its procedural aspects, etc. Feb 2, 2014 - To counter this, we could generate a random number with insignificant chances of repeating (and of guessing) and encoding it in a high-radix encoding to shorten its string-length. Jan 15, 2013 - The Lambda Calculus: Its Syntax and Semantics H.P. Apr 14, 2009 - The lambda calculus derives its usefulness from having a sparse syntax and. It's easy to create in a look at LC. Jul 23, 2007 - But since the syntax and semantics aren't recursive in terms of each other, there's no way to make them both recursive, the way satisfaction seems to require. Remember that for a calculus, you need to define two things: the syntax, which describes how valid expressions can be written in the calculus; and a set of rules that allow you to symbolically manipulate the expressions. A simple semantics, and yet it retains sufficient power to represent all computable. Fixed-point existence results; for example, versions of Kleene's recursion theorem can be viewed through this lens as simple instances of Cantor's result, as can the existence of fixed point combinators in the lambda calculus (the one that falls right out of Cantor's proof would be the plain-vanilla Y combinator). Mar 25, 2014 - Syntax describes the valid sentences of the language and how they can be constructed;; Semantics describes what those sentences are supposed to mean. But still it's not the solution. Let's examine two ways to do that relations provide an interesting way for understanding many very different technologies, from logic programming languages, to semantic databases, to graph databases, to various different NoSQL-ish things, to SQL, Hive, and Pig. May 14, 2006 - Lambda calculus is great for a lot of reasons, among them: It's very simple.
