From 815efcb40d9a2118bec8783513940f0b57c9a094 Mon Sep 17 00:00:00 2001 From: Melvin Alvarez Date: Mon, 16 Feb 2026 17:00:36 +0100 Subject: [PATCH] docs: add notebook execution report Created comprehensive report documenting notebook validation results: - 2/8 notebooks execute successfully (25%) - 2/8 have API mismatches (parameter name changes) - 1/8 has syntax errors (garbage characters) - 3/8 require further investigation The report includes: - Detailed error analysis for each failed notebook - Root cause analysis (API evolution without updates) - Recommended fixes with priorities - Impact assessment on documentation quality - Proposed CI/CD workflow for automated validation Priority: HIGH - Broken examples undermine v1.0.0 credibility. Next steps: Fix high-priority notebooks (MCMC, DE, benchmarks, real-world) --- NOTEBOOK_EXECUTION_REPORT.md | 296 +++++++++++++++++++++++++++++++++++ 1 file changed, 296 insertions(+) create mode 100644 NOTEBOOK_EXECUTION_REPORT.md diff --git a/NOTEBOOK_EXECUTION_REPORT.md b/NOTEBOOK_EXECUTION_REPORT.md new file mode 100644 index 0000000..1a0c0e3 --- /dev/null +++ b/NOTEBOOK_EXECUTION_REPORT.md @@ -0,0 +1,296 @@ +# OptimizR Notebook Execution Report + +**Date**: 2026-02-16 +**Commit**: 6b084ae +**Objective**: Execute all tutorial notebooks and validate documentation examples + +--- + +## ✅ Successfully Executed (2/8) + +### 1. `01_hmm_tutorial.ipynb` ✅ WORKING +- **Status**: All cells executed successfully +- **Output Size**: 397KB (with plots and results) +- **Content**: HMM regime detection examples +- **Features Demonstrated**: + -
