This is the ZJU ICICLES (浙江大学课程攻略共享计划) repository - a massive, student-maintained collection of course materials from Zhejiang University spanning 20+ academic disciplines. The repository contains lecture slides (PPT/PDF), lecture notes (Markdown/LaTeX/Typst), exam papers with solutions, homework assignments with code implementations, lab reports, textbook PDFs, and study guides. While classified as 'data_research' due to the presence of code artifacts in lab directories (compiler construction, data structures, operating systems, computer networks, digital logic), the dominant content is educational courseware - not a data pipeline or ML project. The repository serves as a knowledge base for ZJU students and demonstrates exceptional community curation. Key technical components include: a complete C compiler implementation (lex/yacc + codegen) in 编译原理/实验/, data structure implementations (red-black trees, graph algorithms, B-trees) in 数据结构基础/作业/dsHomework/, RISC-V OS lab code in 操作系统/ and 计算机组成与系统结构/, socket programming labs in 计算机网络/Lab/, and Verilog/FPGA code in 逻辑与计算机设计基础/ and 汇编与接口/. The repository is actively maintained with recent commits, but reproducibility of code artifacts is low due to course-specific dependencies, missing build configurations, and environment assumptions.
