COMP3161/COMP9164 Supplementary Lecture Notes Type Safety and Exceptions Liam O’Connor November 1, 2019 When we define a static semantics for a language, we wish that static semantics to imply some properties about the dynamic semantics. In this notes, we will discuss what properties are, how we can classify them, and the kinds of properties we

COMP3161/COMP9164 Abstract Machines Exercises Liam O’Connor October 20, 2019 1. Decision Machines: Suppose we have a language of nested brackets N (where ε is the empty string): N eNN eNN eNN εN 1 (e)N 2 ⟨e⟩N 3 [e]N 4 Note that ()() is not a string in this language. We developed a simple abstract machine

Composite Data Types as Algebra, Logic Recursive Types 1 Algebraic Data Types Christine Rizkallah CSE, UNSW Term 3 2020 Composite Data Types as Algebra, Logic Recursive Types 2 Composite Data Types Most of the types we have seen so far are basic types, in the sense that they represent built-in machine data representations. Real programming
Natural Deduction Rule Induction Ambiguity Simultaneous Induction 1 Natural Deduction and Rule Induction Dr. Liam O’Connor University of Edinburgh LFCS UNSW, Term 3 2020 Natural Deduction Rule Induction Ambiguity Simultaneous Induction Formalisation To talk about languages in a mathematical way, we need to formalise them. Formalisation Formalisation is the process of giving a language a
COMP3161/COMP9164 Supplementary Lecture Notes Overloading Gabriele Keller, Liam O’Connor November 11, 2019 So far, all the operations we have in MinHS are either monomorphic in that they work on a specific type, as for example addition (+) : Int → Int → Int or they are polymorphic, in that they work on any type at
