Description
Leanstral 1.5 is a model licensed under Apache-2.0, designed for effective proof engineering in Lean 4, aimed at enhancing the capabilities and accessibility of formal verification. It boasts a total of 119 billion parameters, with 6 billion of them being active, marking a significant improvement in performance for tasks such as theorem proving, agent-based proof engineering, and the verification of practical code. The development of Leanstral 1.5 involved a comprehensive three-stage training process, which included mid-training, supervised fine-tuning, and reinforcement learning utilizing CISPO. In a multiturn environment, the model is tasked with receiving a theorem statement, submitting a proof, and refining its approach based on feedback from the Lean compiler until the proof is either successfully compiled or the available resources are depleted. In the code agent setting, Leanstral functions similarly to a developer navigating a raw filesystem, allowing it to edit files, execute bash commands, and interact with the Lean language server to monitor goals, errors, and type information in real time. This innovative approach not only streamlines the proof engineering process but also significantly enhances the user experience in formal verification tasks.
Description
Prolog is a programming language based on logic that is closely linked to the fields of artificial intelligence and computational linguistics. Originating from first-order logic, which is a type of formal logic, Prolog distinguishes itself from many other programming languages by being primarily a declarative language, where logic is conveyed through relations that are defined by facts and rules. To begin a computation, one must execute a query against these established relations. As one of the pioneering logic programming languages, Prolog continues to enjoy widespread popularity today, supported by various free and commercial implementations. This versatile language has found applications in diverse areas such as theorem proving, expert systems, term rewriting, type systems, automated planning, and its foundational purpose of natural language processing. Additionally, contemporary Prolog environments offer capabilities for developing graphical user interfaces, alongside support for both administrative tasks and networked applications, further demonstrating its adaptability in modern programming contexts.
