Alloy theory

Alloy theory is a formal method used in software and system design to model and analyze complex structures and behaviors. It involves creating models with mathematical descriptions called signatures and constraints called facts, which define how different parts relate. Using specialized tools, engineers can automatically check these models for errors or inconsistencies, ensuring the system behaves as intended. Think of Alloy as a precise blueprinting language that helps verify the correctness of systems before they are built, reducing errors and improving reliability early in the design process.
