“ Before you buy a Ferrari to drive to the grocery store, try walking. ”

We built EZR.py: a 400-line Python toolkit, stdlib only, under 1MB to install. On 120+ tabular SE optimization tasks it matches or beats SMAC3, SHAP, LIME, FASTREAD — while running 500× faster on under 100 labels.
How? Read the code. Strip the redundancy. Many "different" algorithms — classification, clustering, optimization, text mining — collapse to the same four classes: Num, Sym, Cols, Data. One-line change flips a decision tree from numeric to symbolic prediction. 1983's Simulated Annealing still beats modern Local Search variants. Naive Bayes in 30 lines beats SVM on text.
| vs. SMAC3 | 500× faster |
| labels to optimum | < 100 |
| features used | < 10 |
| code size | 400 lines |
| install size | < 1 MB |
| tasks tested | 120+ |
Developers still need to read code. At least for tabular optimization.
