xorriso
1.5.8.pl02Terms
- Run
- One campaign of one tool on one program.
- Cores
- The parallel processes of one campaign.
- Budget
- The longest a campaign may run.
- Fixed track
- The command line is given and the tool supplies only the input. Method
- Open track
- The tool also chooses arguments, files and environment. Method
- Median
- The middle value over a tool's runs; the median of two runs is their mean.
- standard
- Conventional gcov replay of every retained test case, same counting code and denominators. Method
- Unreached
- A branch that none of the main-group tools that ran on the program reaches (4 to 12 tools).
- Union of runs
- The branches that at least one of a tool's runs reaches, each counted once.
- Output tokens
- Model output of a whole campaign, reasoning included, as self-reported in the release.
- Sanitiser signature
- The sanitiser, the error kind and the innermost frame in the program's own source; two can share a cause.
- Language model
- A system in which a language model does the central reasoning of a classical technique, such as concolic execution.
- Symbolic
- Runs the program on symbolic inputs and asks a constraint solver for concrete inputs that reach new paths.
- Fuzzer
- Coverage-guided fuzzing: mutates inputs and keeps those that reach new code.
- Hybrid
- A fuzzer paired with a concolic executor; each supplies the other with inputs.
- Main
- Shown by default: the tools a reader is most likely to compare.
- Ablation
- Variants of the agent that switch off or change one part, to show what that part adds.
- Seeding
- Runs of a tool that start from seeds produced by another system.
- Control
- Systems that run without the agent, as a reference for the main group.
- Release
- A dated snapshot of the data, named like 2026.1. It never changes; corrections go into the next release.
- Superseded
- An entry that a newer one replaces. It stays in the release and shows under all versions.
- Withdrawn
- An entry taken out of the comparison after it was published.
GNU xorriso creates and changes ISO 9660 file system images with Rock Ridge extensions and can write them to optical media.
