# Show HN: ZUSE – 69x causal compression of a period-15 CA oscillator > Source: > Published: 2026-06-29 13:37:33+00:00 Deterministic empirical law discovery for elementary cellular automata (ECA). ZUSE Automat Agent runs cellular-automata worlds, applies a fixed observer stack, evaluates seven binary cycle laws, and stores multi-seed evidence in reproducible journals. The discovery loop is policy-driven and deterministic: no language model participates in world selection, law evaluation, scoring, or acceptance. **Latest: v1.11** - Early causal-cone compression of the T=15 mechanism: 25 cells for 12 steps recover `defect_state0` in 20/20, a 69.1x reduction. - v1.11 DOI: [10.5281/zenodo.21034813](https://doi.org/10.5281/zenodo.21034813) - v1.10 DOI: [10.5281/zenodo.21009303](https://doi.org/10.5281/zenodo.21009303) - v1.9 DOI: [10.5281/zenodo.21001633](https://doi.org/10.5281/zenodo.21001633) - v1.8 DOI: [10.5281/zenodo.21000646](https://doi.org/10.5281/zenodo.21000646) - v1.7 DOI: [10.5281/zenodo.20971738](https://doi.org/10.5281/zenodo.20971738) - v1.6 DOI: [10.5281/zenodo.20792051](https://doi.org/10.5281/zenodo.20792051) - v1.5 DOI: [10.5281/zenodo.20768585](https://doi.org/10.5281/zenodo.20768585) - v1.4 DOI: [10.5281/zenodo.20767477](https://doi.org/10.5281/zenodo.20767477) - v1.3 DOI: [10.5281/zenodo.20753499](https://doi.org/10.5281/zenodo.20753499) - v1.2 DOI: [10.5281/zenodo.20738025](https://doi.org/10.5281/zenodo.20738025) - v1.1 DOI: [10.5281/zenodo.20687470](https://doi.org/10.5281/zenodo.20687470) - v1.0 DOI: [10.5281/zenodo.20516375](https://doi.org/10.5281/zenodo.20516375) - v1.11 series DOI: [10.5281/zenodo.21034812](https://doi.org/10.5281/zenodo.21034812) - v1.10 series DOI: [10.5281/zenodo.21009302](https://doi.org/10.5281/zenodo.21009302) - v1.9 series DOI: [10.5281/zenodo.21001632](https://doi.org/10.5281/zenodo.21001632) - v1.8 series DOI: [10.5281/zenodo.21000645](https://doi.org/10.5281/zenodo.21000645) - v1.7 series DOI: [10.5281/zenodo.20971737](https://doi.org/10.5281/zenodo.20971737) - v1.6 series DOI: [10.5281/zenodo.20792050](https://doi.org/10.5281/zenodo.20792050) - v1.5 series DOI: [10.5281/zenodo.20768584](https://doi.org/10.5281/zenodo.20768584) - v1.4 series DOI: [10.5281/zenodo.20767476](https://doi.org/10.5281/zenodo.20767476) - v1.3 series DOI: [10.5281/zenodo.20753498](https://doi.org/10.5281/zenodo.20753498) - Previous-series DOI (v1.2 and earlier): [10.5281/zenodo.20738024](https://doi.org/10.5281/zenodo.20738024) - PDF: [paper/zuse_preprint.pdf](/conchaestradamiguelangel-droid/zuse-automat-agent/blob/master/paper/zuse_preprint.pdf) [World taxonomy and law coverage matrix](/conchaestradamiguelangel-droid/zuse-automat-agent/blob/master/outputs/world_taxonomy/law_map.md): formal classification of 20 worlds, seven-law coverage, and measured fragility where available.[Scientific synthesis](/conchaestradamiguelangel-droid/zuse-automat-agent/blob/master/outputs/scientific_synthesis/FINDINGS.md): consolidated findings across world families, law coverage, fragility mechanisms, and open questions.[Physical-tree findings](/conchaestradamiguelangel-droid/zuse-automat-agent/blob/master/outputs/pysr_fase7/FINDINGS.md): meta-analysis of physical metrics that predict law richness.[Fragility report](/conchaestradamiguelangel-droid/zuse-automat-agent/blob/master/outputs/fragility_fase10/fragility_report.md): basin fragility spectrum and observed mechanisms.[Rule 54 noise-gate anatomy](/conchaestradamiguelangel-droid/zuse-automat-agent/blob/master/outputs/rule54_gate_fase13/rule54_gate_report.md): diagnosis of the dedup noise-boundary mechanism.[Local oscillator family sweep](/conchaestradamiguelangel-droid/zuse-automat-agent/blob/master/outputs/local_oscillator_family_fase18/local_oscillator_family_report.md): exhaustive quiescent ECA sweep;`rule_108` is unique under the current local oscillator protocol.[Periodicity sweep](/conchaestradamiguelangel-droid/zuse-automat-agent/blob/master/outputs/periodicity_fase21/periodic_ic_sweep_report.md): designed periodic ICs validate`periodicidad` across ECA. ``` python -m venv .venv .\.venv\Scripts\Activate.ps1 pip install -r requirements.txt ``` Run a simulation: ``` python -m zaa simulate --rule 110 --steps 200 --width 256 --out outputs\rule110 ``` Run a short deterministic discovery loop: ``` python -m zaa discover --world rule_110 --cycles 5 --journal journal.jsonl ``` Run the test suite: ``` python -m unittest discover -s tests ``` See [REPRODUCIBILITY.md](/conchaestradamiguelangel-droid/zuse-automat-agent/blob/master/REPRODUCIBILITY.md) for the commands used to regenerate the atlas, fragility reports, oscillator sweeps, and periodicity results.
