GISMOL: A General Intelligent Systems Modelling Language

This paper presents GISMOL (General Intelligent System Modelling Language), a Python-based framework implementing Constrained Object Hierarchies (COH)—a neuroscience-inspired theoretical framework for Artificial General Intelligence (AGI). COH and GISMOL together provide a unified language for modelling and implementing intelligent systems across diverse domains including healthcare, manufacturing, finance, and governance. The framework bridges symbolic AI and neural computation through its core architecture of constraint-aware objects with embedded neural components, hierarchical reasoning capabilities, and natural language integration. We demonstrate how GISMOL translates COH’s formal 9-tuple representation into executable systems with six comprehensive case studies, showing its versatility in modelling complex intelligent behaviors while maintaining theoretical rigor. The implementation includes specialized modules for neural integration, multi-domain reasoning, and natural language processing, all built around the COHObject abstraction that encapsulates intelligence as constrained hierarchical structures.
