LCF: Automated generic theorem prover
Cambridge LCF (Logic for Computable Functions) is an interactive
theorem prover. Proofs are conducted in PPLAMBDA, a natural deduction
logic based on the domain theory of Dana Scott. PPLAMBDA is
particularly suitable for proofs involving denotational semantics,
lazy evaluation, or higher-order functions. LCF provides a
metalanguage (Standard ML), a functional programming language whose
values include PPLAMBDA terms, formulas, and theorems.
Theorem-proving primitives such as inference rules, subgoaling
strategies (tactics), and simplifiers are implemented as ML functions.
The user can extend LCF by programming in ML.
[LCF is an obsolete system.]
