요약	Head-Driven Phrase Structure Grammar (HPSG) is a constraint-based grammatical framework developed by Carl Pollard and Ivan Sag in 1987. HPSG represents linguistic information (phonological, syntactic, semantic) in typed feature structures and derives well-formed expressions through constraints on these structures. Unlike movement-based theories, HPSG models word order and long-distance dependencies through feature sharing and principles of grammar. It has been extensively applied to modeling diverse language phenomena and remains influential in computational linguistics.	The Minimalist Program (MP) is a framework for generative syntax developed by Noam Chomsky in 1995, designed to explain linguistic structure while assuming the fewest possible theoretical mechanisms. The program seeks principles that are simple, elegant, and motivated by language evolution. It addresses core questions: What principles explain language structure? Why do languages vary? Why do humans have language? The MP has become the dominant paradigm in theoretical syntax, though it remains controversial and subject to ongoing refinement.	Optimality Theory (OT) is a constraint-based framework for modeling phonology and syntax, developed by Alan Prince and Paul Smolensky in 1993. The core idea is that languages produce the optimal output that best satisfies a ranked hierarchy of universal constraints. Rather than listing rules, OT explains linguistic phenomena as solutions to conflicting pressures—sounds and structures emerge as the least bad compromise among competing demands. This framework has revolutionized phonological theory and is widely applied to morphophonology, segmental and suprasegmental analysis, and cross-linguistic variation.
