Formal models and scripts: spatial-extras

Tools: Python

These are the working models and scripts this part of the hunt used. Some encode the code as it is (a counterexample is the expected result), others a fixed or correct variant; read the header comment of each file. Paths inside them were replaced by placeholders such as $LUCENE (a Lucene checkout) and $WORK.

Findings

• BBoxStrategy's overlap-ratio relevance (BBoxOverlapRatioValueSource) undercounts the overlap of two dateline-crossing boxes that intersect in two longitude pieces, so the score is too low (finding LFV-369; repro · finding page)

Files

• bbox-overlap-ratio-two-piece-dateline-intersection/model/smt/overlap_ratio_fp.py (used for LFV-369)
• bbox-overlap-ratio-two-piece-dateline-intersection/model/smt/overlap_ratio_fp_ge1.py (used for LFV-369)

How to run

• Python: python3 <file>.py; scripts that import z3 need the z3-solver package.
