Equality and uninterpreted function
WebThe logic of equality with uninterpreted functions has been proposed for verifying abstract hardware designs. The ability to perform fast satisfiability checking over this logic is imperative for such verification paradigms to be successful. We present symbolic methods for satisfiability checking for this logic.

WebFollowing [26], we call this extension the theory of equality logic and uninterpreted functions (EUF). For example :(a = b) _f(a) = f(b) is an EUF formula containing the uninterpreted functions a;b, and f, embedded in a Boolean structure.
Webinterpreted functions. FCEDs can represent values of expressions in a program involving conditionals and linear arithmetic (or uninterpreted functions). We show how to construct them easily from a program, and give a randomized linear time algorithm (or quadratic time for uninter-preted functions) for comparing FCEDs for equality. FCEDs are compact WebLecture 9: Theory of equality and uninterpreted functions (QF EUF) Instructor: Ashutosh Gupta IITB, India Compile date: 2024-09-19.

WebUninterpreted Functions Every function is a mapping from a domain to a range. Example: the ’+’ function over the naturals, N, is a mapping from N x N to N.

WebEUF: Equality and Uninterpreted Functions. The logic of equality and uninterpreted function, EUF, is a basic ingredient for first-order predicate logic. Before there are theories, there are constants, functions and predicate symbols, and the built-in relation of equality. In the following example, f is a unary function, x a constant.
