The Ultimate Life Function (ULF): Original Formulation

Abstract The Ultimate Life Function (ULF) is a formal theoretical framework that models human optimality across time as an integral function of experiential value and system sustainability. The framework proposes that long-term human flourishing can be mathematically expressed as a continuous optimization process integrating well-being dynamics, resilience, and adaptive stability. ULF connects concepts from neuroscience, psychology, systems theory, and control theory into a unified structure. It provides a mathematical perspective on life optimization, decision-making, and sustainable cognitive states. This document represents the original formulation of the ULF framework and serves as a canonical reference for future theoretical development.
