Intelligence as Trajectory-Dominant Pareto Optimization

TL;DR

This paper presents a new framework for understanding intelligence as a trajectory-level multi-objective optimization problem, revealing structural constraints like Pareto traps that limit long-term adaptability regardless of learning progress.

Contribution

It introduces Trajectory-Dominant Pareto Optimization and the concept of Pareto traps, providing a geometric perspective on long-horizon limitations in adaptive systems.

Findings

Pareto traps restrict access to superior developmental paths.

Dynamic intelligence ceilings are geometric consequences of trajectory dominance.

The framework enables diagnosing and overcoming long-term developmental constraints.

Abstract

Despite recent advances in artificial intelligence, many systems exhibit stagnation in long-horizon adaptability despite continued performance optimization. This work argues that such limitations do not primarily arise from insufficient learning, data, or model capacity, but from a deeper structural property of how intelligence is optimized over time. We formulate intelligence as a trajectory-level phenomenon governed by multi-objective trade-offs, and introduce Trajectory-Dominant Pareto Optimization, a path-wise generalization of classical Pareto optimality in which dominance is defined over full trajectories. Within this framework, Pareto traps emerge as locally non-dominated regions of trajectory space that nevertheless restrict access to globally superior developmental paths under conservative local optimization. To characterize the rigidity of such constraints, we define the Trap Escape Difficulty Index (TEDI), a composite geometric measure capturing escape distance, structural constraints, and behavioral inertia. We show that dynamic intelligence ceilings arise as inevitable geometric consequences of trajectory-level dominance, independent of learning progress or architectural scale. We further introduce a formal taxonomy of Pareto traps and illustrate the resulting trajectory-level divergence using a minimal agent-environment model. Together, these results shift the locus of intelligence from terminal performance to optimization geometry, providing a principled framework for diagnosing and overcoming long-horizon developmental constraints in adaptive systems.
