Decision Systems

Opening — Why this matters now The AI industry has developed an unfortunate habit: celebrating systems that usually work. From large language models hallucinating citations to reinforcement learning agents missing obvious optimal moves, the pattern is familiar—impressive performance, quietly unreliable guarantees. This paper, “Completeness of Unbounded Best-First Minimax and Descent Minimax” fileciteturn0file0, addresses a deceptively narrow issue in game search algorithms. But underneath, it tackles something far more uncomfortable: ...

Opening — Why this matters now There is a quiet shift happening in AI—not in model size, but in how models think. For the past two years, the industry has optimized reasoning by refining prompts: Chain-of-Thought, Tree-of-Thoughts, Graph-of-Thoughts. Each iteration made reasoning more structured, more deliberate, more… verbose. But underneath the surface, the paradigm remained unchanged: reasoning is still a temporary, disposable process. ...
