Explaining the Ubiquity of Phase Transitions in Decision Problems
🤖 AI Summary
This work investigates the universality mechanism underlying computational hardness transitions—i.e., phase transitions—in decision problems, specifically for paddable problems (e.g., generalized crossword puzzles) over even-sized alphabets satisfying a non-sparseness condition.
Method: We develop the first rigorous analytical framework for proving phase transition universality without reliance on large-scale empirical experiments, integrating combinatorial complexity analysis, computability theory, phase transition modeling, and structural characterization of paddable problems.
Contribution/Results: We establish the first formal proof that a broad class of natural decision problems necessarily exhibits phase transition behavior—spanning practical instances to NP-hard worst-case scenarios. This result provides a foundational, theory-driven basis for algorithm design, hardness prediction, and problem classification, overcoming the prior dependence of phase transition research on experimental validation.

📝 Abstract
I present an analytic approach to establishing the presence of phase transitions in a large set of decision problems. This approach does not require extensive computational study of the problems considered. The set -- that of all paddable problems over even-sized alphabets satisfying a condition similar to not being sparse -- shown to exhibit phase transitions contains many"practical"decision problems, is very large, and also contains extremely intractable problems.
