Nettet2. sep. 2024 · The AKS algorithm (by Agrawal, Kayal and Saxena) is a significant theoretical result, establishing “PRIMES in P” by a brilliant application of ideas from finite fields. This paper describes an implementation of the AKS algorithm in our theorem prover HOL4, together with a proof of its correctness and its computational complexity. … NettetJitawa was designed to host Jared Davis' Milawa theorem prover — a prover which we have formally proved to be sound when run on Jitawa.

Other interactive theorem provers we could have based a learning environment on include Mizar (Mizar), Is-abelle (Wenzel et al.,2008), HOL4 (Slind & Norrish,2008), and Lean (de Moura et al.,2015).

After all, there is no way to formalize the correctness of a theorem prover build in the real world since the most we can do is to express that notion in some syntactic form that intuitively seems to correspond to what we want it to mean. And then of course under … NettetThe logics of most proof assistants for higher-order logic (Coq, Isabelle/HOL, HOL4, PVS, etc.) contain subsets which closely resemble pure functional programming languages. As a result, it has become commonplace to verify functional programs by ﬁrst coding up algorithms as functions in a theorem prover’s logic, then using the prover to ... ud flyer football schedule

Proof obligations are passed from the interactive HOL4 prover to the SMT solver, which can often prove them automatically.

The Isabelle automated theorem prover is a higher-order logic (HOL) theorem prover, written in Standard ML and Scala. As an LCF-style theorem prover, it is based on a small logical core (kernel) to increase the trustworthiness of proofs without requiring — yet supporting — explicit proof objects. Isabelle is available inside a flexible system framework allowing for logically s… NettetWe implement Lassie as a library for the HOL4 [32] ITP system, but our technique is applicable to other theorem provers as well. Lassie is fully compatible with standard HOL4 proofs. Since all Lassie tactics map to standard HOL4 tactics, Lassie allows exporting a Lassie proof into standard HOL4 to maintain portability of proofs. On the …

A number of HOL systems (sharing essentially the same logic) remain active and in use: 1. HOL4 — the only presently maintained and developed system stemming from the HOL88 system, which was the culmination of the original HOL implementation effort, led by Mike Gordon. HOL88 included its own ML implementation, which was in turn implemented on top of Common Lisp. The systems that followed HOL88 (HOL90, hol98 and HOL4) were all implemented in Standar…
