Skyline-First Traversal as a Control Mechanism for Multi-Criteria Graph Search
Nicolas Tacheny
In multi-criteria graph traversal, paths are compared via Pareto dominance, an ordering that identifies which paths are non-dominated, but says nothing about which path to expand n…

Geometric Dynamics of Agentic Loops in Large Language Models
Nicolas Tacheny
Iterative LLM systems(self-refinement, chain-of-thought, autonomous agents) are increasingly deployed, yet their temporal dynamics remain uncharacterized. Prior work evaluates task…

Calibrated Similarity for Reliable Geometric Analysis of Embedding Spaces
Nicolas Tacheny
While raw cosine similarity in pretrained embedding spaces exhibits strong rank correlation with human judgments, anisotropy induces systematic miscalibration of absolute values: s…
