Learning-assisted automated reasoning has recently gained popularity among the users of Isabelle/HOL, HOL Light, and Mizar. In this paper, we present an add-on to the HOL4 proof assistant and an adaptation of the HOL(y)Hammer system that provides machine learning-based premise selection and automated reasoning also for HOL4. We efficiently record the HOL4 dependencies and extract features from the theorem statements, which form a basis for premise selection. HOL(y)Hammer transforms the HOL4…

Sharing HOL4 and HOL Light Proof Knowledge
TLDR
A number of methods are proposed and evaluated, which strengthen proof automation by learning from proof libraries of different provers, which can be proved directly from the dependencies induced by similar proofs in the other library.
TacticToe: Learning to Reason with HOL4 Tactics
TLDR
A unified proof assistant automation approach which attempts to automate the selection of appropriate tactics and tactic-sequences with an optimized small-scale hammering approach, implemented as a tactic-level automation for HOL4: TacticToe.
Thor: Wielding Hammers to Integrate Language Models and Automated Theorem Provers
TLDR
Thor is introduced, a framework integrating language models and automated theorem provers to overcome this challenge of selecting useful premises from a large library to unlock the proof of a given conjecture.
Improving automation in interactive theorem provers by efficient encoding of lambda-abstractions
TLDR
Developing algorithms which outperform both lambda-lifting and the simple Scho ̈nfinkel’s algorithm used in Sledgehammer for Isabelle/HOL, thus enhancing au- tomation in proof assistants.
Certified Connection Tableaux Proofs for HOL Light and TPTP
TLDR
This paper shows how theLeanCoP's core algorithm can be implemented inside HOL Light, providing an implementation of leanCoP that certifies its proofs, and discusses the differences between the direct implementation using an explicit Prolog stack, to the continuation passing implementation of MESON present in HOL Light.
A Learning-Based Fact Selector for Isabelle/HOL
TLDR
This work introduces MaSh, an alternative that learns from successful proofs, and outperforms the old fact selector on large formalizations.
Proof searching and prediction in HOL4 with evolutionary/heuristic and deep learning techniques
TLDR
Experimental results suggest that combining evolutionary/heuristic and deep learning techniques with proof assistants can greatly facilitate proof finding/optimization and proof prediction.
Hammering towards QED
This paper surveys the emerging methods to automate reasoning over large libraries developed with formal proof assistants. We call these methods hammers. They give the authors of formal proofs a…
Property Invariant Embedding for Automated Reasoning
TLDR
This work proposes a novel encoding of formulas that extends existing graph neural network models and provides additional links between such nodes that allow the network to recover the meaning and therefore correctly embed such nodes irrespective of the given labels.
GRUNGE: A Grand Unified ATP Challenge
TLDR
A large set of related theorem proving problems obtained by translating theorems from the HOL4 standard library into multiple logical formalisms results in a new "grand unified" large theory benchmark that emulates the ITP/ATP hammer setting.

Automated Reasoning in Higher-Order Logic using the TPTP THF Infrastructure
