Run 1776702466 ​

Trial run

Warning — trial run. This benchmark was executed with fewer than 10 instances per fuzzer and/or a time budget shorter than 24h. Results from trial runs are meant for debugging purposes and are not valid for extracting conclusions across different fuzzers.

Report ​

Fuzzer Benchmark Report (from bug-count CSV) ​

  • Time budget: 1.00h

Warning — trial run. This benchmark was executed with fewer than 10 instances per fuzzer and/or a time budget shorter than 24h. Results from trial runs are meant for debugging purposes and are not valid for extracting conclusions across different fuzzers.

Executive summary ​

This report is derived solely from cumulative bugs-found over time across repeated runs per fuzzer. It emphasizes robust, distribution-based metrics (median/IQR, success rates, time-to-k) and shape-based behavior (plateau time, late discovery share) instead of single-run time-to-first-bug.

Throughput metrics (if supported by log format) ​

Values are run-level rates aggregated per fuzzer; n/a indicates the parser could not recover that metric from logs.

Progress metrics from logs (fuzzer-specific proxies) ​

Coverage/corpus values are parsed from each fuzzer's native progress output and are useful for trend context, not strict cross-fuzzer equivalence.

Statistical comparison (Mann-Whitney U test) ​

Pairwise Mann-Whitney U tests on end-of-budget bug counts (two-sided). Bonferroni correction applied for 3 comparison(s). Significance level: alpha = 0.05.

Warnings:

  • One or more fuzzers have fewer than 5 runs. Statistical power may be limited.
Fuzzer AFuzzer BMedian AMedian BU statisticp-valuep (corrected)Significant

recon-fuzzermedusa552.01.00001.0000no
echidnamedusa552.01.00001.0000no

No pairwise comparison reached significance after Bonferroni correction.

Note: The Mann-Whitney U test assesses whether one fuzzer tends to find more bugs than another across runs. It does not measure effect size or practical importance. Small sample sizes (fewer than 5 runs) reduce statistical power.

Shape-based interpretation (rules of thumb) ​

  • Fast-start / early-plateau: high early checkpoint median + early plateau time + low late discovery share.
  • Steady: moderate AUC, later plateau, consistent improvements across checkpoints, moderate variance.
  • Slow-burn / late-surge: low early checkpoints but high late discovery share and later plateau time; often higher final median.

Limitations ​

  • Core metrics in this section are count-based; use broken_invariants.md / broken_invariants.csv for invariant identities.
  • Severity, exploitability, and root-cause uniqueness cannot be measured directly without richer per-bug metadata.
  • Harness design still affects results; mitigate by keeping harness identical across fuzzers and reporting many runs.

Broken invariants ​

  • Budget filter: 1.00h
  • Events considered: 30 / 30
  • Unique invariants: 5

Warning — trial run. This benchmark was executed with fewer than 10 instances per fuzzer and/or a time budget shorter than 24h. Results from trial runs are meant for debugging purposes and are not valid for extracting conclusions across different fuzzers.
