Scientific & Philosophical Articles

Research & Publications

Peer-reviewed publications on combinatorial optimization and the philosophy of computation.

15-Second Overview

One Program, Three Fronts

I seek unity in diversity. I am not interested in accumulating topics; I pursue a single question from multiple angles: how we think, justify, and control algorithmic systems, and now LLMs, when knowledge is partial and error is structural.

Technical Core

Optimization Under Constraints

Design and analysis of intelligent optimization methods. Instances include metaheuristics and LLM-assisted optimization pipelines.

Selected work

Software Core

Analytical Tooling & Infrastructure

Development of tools that make algorithmic behavior inspectable and reproducible. Instances include STN Analytics and related visualization frameworks.

Selected work

Philosophical

Philosophy of Artificial Fallibility

A philosophical framework centered on Architectures of Error, comparing how human and AI systems generate, justify, and propagate mistakes in code.

Selected work

Intellectual Cartography
