Literature Review Paper

I need a 20–30-page, single-column review paper in the official Elsevier LaTeX format, prepared directly in Overleaf, that critically synthesises recent peer-reviewed work on large language models and generative AI. The paper must compare and contrast existing studies, highlight where authors agree or disagree, expose gaps in the literature, and close with my own well-argued perspective on promising directions for future research. No new experiments are required; the value lies in rigorous analysis, clear structure, and a scholarly narrative that demonstrates breadth and depth of reading across the field. Key expectations • Use only up-to-date, peer-reviewed sources (journals, top-tier conferences, or reputable archives). • Follow Elsevier guidelines exactly—no table of contents, accurate citation style, consistent figure/table formatting, and clean LaTeX code. • Provide both the Overleaf project link (for live editing) and the final compiled PDF. • Ensure language is polished, cohesive, and accessible to an academic computer-science audience while maintaining critical insight. Completion is defined by a fully formatted .tex project and a ready-to-submit PDF that meet the above criteria.
