📝 Translation Quality

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

Summary: The translation of the Implementation, Simulation, and Exercises sections is accurate, fluent, and terminologically consistent with the glossary. Code, math, and MyST directive formatting are well preserved with no syntax errors. Only minor stylistic nitpicks were found; no accuracy or terminology blockers exist in the changed sections. Code blocks, LaTeX math, and MyST directives are preserved accurately across the Implementation, Simulation, and Exercises sections Technical terminology (基尼系数, 平稳分布, 内生网格, 时间迭代) is consistent with the glossary and prior sections of the document Comments within code cells are naturally and accurately translated, maintaining code functionality and readability Exercise and solution blocks are fluently translated with correct academic register and consistent formatting

Suggestions:

• [minor · formatting] lectures/ifp_advanced.md — ### Setting up doc reference in Implementation section context (footnote about ifp_egm_transient_shocks): The English source references {doc}ifp_egm_transient_shocks without a namespace prefix, but the translation adds intermediate: prefix (e.g., {doc}intermediate:ifp_egm_transient_shocks``). This is outside the marked changed sections (it's in an unchanged part near 'Set Up'), so it is not counted against the changed sections, but flagged for awareness only if within scope.
• [minor · fluency] lectures/ifp_advanced.md — ## Implementation, docstring: 'Create an instance of IFP with the given parameters.': The docstring translation '使用给定参数创建一个 IFP 实例。' is accurate and fluent; no issue. (No finding, retained only as confirmation of quality checked.)
• [nit · fluency] lectures/ifp_advanced.md — ## Simulation, 'Bearing in mind that we are looking at log values...' paragraph: Translation '请记住我们看的是对数值' is slightly informal compared to the more academic register used elsewhere; consider '请注意，我们这里查看的是对数值' for consistency with academic tone, though current version is acceptable. → 请注意，我们这里观察的是对数值，直方图表明该分布存在较长的右尾。

Summary: The target document correctly mirrors the source's parameter-order swap in the K function and all solve_model call sites, with no unnecessary changes to structure, headings, or metadata.

Pull request overview

This translation-sync PR updates the ifp_advanced lecture to align the ordering of the EGM/Coleman-Reffett operator inputs/outputs with the convention used across the EGM lectures: (c, a) rather than (a, c).

Changes:

• Reordered K’s arguments and return values to (c, a) and updated solve_model to propagate that ordering.
• Updated all downstream solve_model call sites and variable unpacking to match the (c_vec, a_vec) convention.
• Refreshed translation sync state metadata (source-sha, synced-at).

Reviewed changes

lectures/ifp_advanced.md	Aligns operator/solver interfaces and all call sites to the (c, a) convention used in related EGM lectures.
.translate/state/ifp_advanced.md.yml	Updates translation sync metadata to the new source commit and sync date.
