Ostrich Benchmark Report — Z3 c3 branch

Date: 2026-03-23
Branch: c3 (commit ced7952)
Benchmark set: Ostrich — all 299 files from tests/ostrich.zip
Timeout: 5 seconds per benchmark (-T:5 for Z3 seq/nseq; -t:5000 for ZIPT)
Z3 version: 4.17.0 — build ced7952a7b51a8a8079b6469710326549d558dca
ZIPT: built from parikh branch of CEisenhofer/ZIPT against Z3 .NET bindings (net8.0)

Summary

Metric	seq solver	nseq solver	ZIPT solver
sat	200	205	73
unsat	75	65	37
unknown	24	24	9
timeout	0	0	0
bug/crash	0	5	180
Total time (s)	106.115	117.509	176.134
Avg time/benchmark (s)	0.355	0.393	0.589

Soundness disagreements (any two solvers return conflicting sat/unsat): 22

Note on ZIPT bugs: ZIPT reported bug/crash on 180 benchmarks (60%). Inspection shows ZIPT does not support several Z3 string operations used in this benchmark set (transducers, str.replace_re, str.to_int, str.from_int, str.indexof, str.substr with complex arguments, quantifiers, ADT sorts, etc.). These are counted as crashes/unsupported rather than sound verdicts.

Soundness Disagreements (Critical) — 22 files

The following 22 benchmarks have at least two solvers returning conflicting sat/unsat verdicts. Cases where nseq disagrees with seq on benchmarks named *unsat* or where ZIPT disagrees may indicate soundness bugs.
