This official past paper for the "Theory of Automata" (CSTA-347) course provides an essential study resource for BS Computer Science students in their sixth semester at the National University of Modern Languages (NUML). Capturing the depth of the 2024 Final Examination, this paper rigorously tests core concepts of formal languages, computational models, and complexity theory. Students will find comprehensive questions focusing on Deterministic and Non-Deterministic Finite Automata (DFA/NFA), regular expressions, Context-Free Grammars (CFG), Pushdown Automata (PDA), and Turing Machines. By practicing with these exam-style questions, learners can evaluate their understanding of the Chomsky hierarchy, pumping lemmas for regular and context-free languages, and the conversion processes between different computational machines. This past paper serves as an invaluable diagnostic tool to identify knowledge gaps, master time management during examinations, and grasp the typical structural pattern of NUML’s final assessments. Reviewing these structural problems enhances logical reasoning and analytical skills, which are crucial for success in compiler construction and advanced algorithm design, ultimately preparing students to excel in their final exams.

The CSTA-347 syllabus abstract outlines the theoretical foundations of computation. This final exam paper targets key domains, including regular languages, transition graphs, grammar simplification, Chomsky Normal Form, and parsing techniques. It balances theoretical proof methodologies, such as the pumping lemma, with practical construct design, like building minimum-state DFA machines and designing Turing machines for complex languages. Through a structured mix of objective design scenarios and subjective analytical proofs, this paper mirrors the standard NUML examination pattern, evaluating a student’s capability to formalize computational processes, optimize language models, and analyze mathematical structures in computer science.
