#1068 - [house_auction] Add VCG comparison section and exercises

Files Updated

• ✏️ lectures/house_auction.md
• ✏️ .translate/state/house_auction.md.yml
• ✏️ lectures/_static/quant-econ.bib

⚠️ Target-Only Sections Removed

The following sections exist in the current translation but have no counterpart in the source document, so this sync removes them (the translation mirrors the source's structure). If the source deleted these sections, this removal is correct — merge as usual. If they are human-authored additions you want to keep, move them into a target-only file before merging (see adding content to a translated edition).

📝 Translation Quality

Criterion	Score
Accuracy	8/10
Fluency	8/10
Terminology	8/10
Formatting	9/10
Overall	8.2/10

Summary: 翻译整体质量较高，准确传达了原文关于拍卖机制和VCG机制比较的核心内容，专业术语基本遵循术语表且前后一致，MyST格式和代码块保留完整。存在少量代码内中文字符串参数顺序错误（影响输出结果，建议修正）、个别输出字符串未翻译导致双语混用，以及列表嵌套层级格式上的小瑕疵，属于次要问题，不影响整体理解和文档编译。 核心经济学和拍卖机制相关术语（如“升价拍卖”“VCG机制”“社会成本”“外部性”）翻译准确且与术语表保持一致 长段落的技术说明和算法伪代码翻译流畅，保留了原文的逻辑结构和数学公式格式 代码块、LaTeX公式及MyST指令（如{cite:t}、{eq}、{ref}、{exercise}）均完整保留，格式正确

Suggestions:

• [minor · fluency] lectures/house_auction.md — ### Basic setting - bullet list after '有$m$个潜在的合格买家': 原文中“Each potential buyer is permitted to buy at most one house.”属于子项目符号层级，但翻译中“每个潜在买家最多只能购买一套房屋。”未使用缩进的子列表符号，导致列表层级结构与原文不一致（丢失了嵌套的二级缩进标记）。 → 保留原始的二级缩进列表格式，例如使用“ * 每个潜在买家最多只能购买一套房屋。”
• [minor · accuracy] lectures/house_auction.md — log("House %i is sold to buyer %i at price %i"...) 的中文翻译: 代码注释被翻译为中文字符串 "房屋%i以价格%i卖给了买家%i"，但参数顺序被调换（原始代码中格式化参数顺序为 i[0], j[0], p[i[0]]，即房屋、买家、价格；而翻译后的字符串写成 i[0], p[i[0]], j[0]），这会导致输出显示错位，价格和买家编号互换。 → 修正为 log("房屋%i以价格%i卖给了买家%i"%(i[0], p[i[0]], j[0])) 或者将字符串顺序改为 "房屋%i卖给了买家%i，价格为%i"%(i[0], j[0], p[i[0]])，确保格式化顺序与字符串描述一致
• [minor · fluency] lectures/house_auction.md — check_terminal_condition 函数内 print('auction ends:', ...): 该行输出字符串 'auction ends:' 未被翻译成中文，与周围已翻译的中文输出（如 print('拍卖结束，因为每个买家都得到了一个房屋。')）不一致，造成双语混杂。 → 翻译为 print('拍卖结束：', not loser_decision.any())
• [nit · terminology] lectures/house_auction.md — ### 第一轮 小节 '买家3有50%的概率被选为房屋2的赢家': 术语“赢家”和“获胜者”在全文中交替使用（如“赢家”“获胜者”“winner_list”相关输出译为“获胜者”），虽不影响理解，但可考虑统一为“获胜者”以保持术语一致性。 → 统一使用“获胜者”替代“赢家”，例如“买家3有50%的概率被选为房屋2的获胜者”
