FuzzBench: pinky13 report

(experiment incomplete/still running...)
warning
Please consider this as a preliminary report to demonstrate the capabilities of FuzzBench. While we have tried our best, we have not confirmed that we configured everything correctly. We are hoping to work together with the community to validate results and improve the set of fuzzers, benchmarks, and their configurations in the future. See FAQ for more details.

experiment summary

No aggregate ranking as the data contains a single benchmark.
  • Median relative code-coverages on each benchmark

    Note: The relative coverage summary table shows the median relative performance of each fuzzer to the experiment maximum. Thus the highest relative performance may not be 100%.
    trial_relative_coverage = trial_coverage / experiment_max_coverage

    app_wrs_rf_new app_stable app_wrs_rf_old
    FuzzerMedian 97.31 89.77 85.29
    FuzzerMean 97.31 89.77 85.29
    bloaty_fuzz_target 97.31 89.77 85.29
    • Fuzzers are sorted by "FuzzerMean" (average median relative coverage), highest on the left.
    • Green background = highest relative median coverage.
    • Blue gradient background = greater than 95% relative median coverage.

    Vargha-Delaney A12 measure
    The table summarizes the A12 values from the pairwise Vargha-Delaney A measure of effect size. Green cells indicate the probability the fuzzer in the row will outperform the fuzzer in the column.
    Mann-Whitney U test
    The table summarizes the p values of pairwise Mann-Whitney U tests. Green cells indicate that the reached coverage distribution of a given fuzzer pair is significantly different.
