Rules & Eligiblity
Who can enter & what's allowed
Rules & Eligibility
By registering or submitting, you agree to these Rules. They govern both phases of the OPTIMAS x NeSy 2025 Neuro-Symbolic Reasoning Hackathon. If anything here conflicts with local law, local law prevails. We may make reasonable updates for clarity or legal compliance (we'll post changes on this site/Discord). All deadlines are AoE (UTC-12).
Who can Participate
Language: English
Professionals & Students
Professionals & Students in AI/ML, NLP, Knowledge graphs, reasoning, data/graph engineering, operations research.
1-5 Members
Teams of one to five members collaborate, innovate, and compete together. (Team setup will be live soon; solo entries are always allowed.)
Phase 1: Design First
Phase One focuses on a design-first approach, without requiring production code.
Phase 2: Finalist
Phase Two challenges finalists to develop and demonstrate a functional prototype.

Tracks & Scope
This is a Neurosymbolic event. Purely procedural/SQL-only entries are out of scope. Your solution must use the provided ontology and show explicit reasoning via classes / properties / relations.
Choose one or more of the following tracks (submit one Approach per chosen track):
- Natural-Language → Ontology Querying
- Causal Reasoning for Disruptions (Deterministic ± Probabilistic)
- Ontology Evolution from Integration Data
All tracks follow the Air-gapped rule: submissions used for judging must run locally with no internet access.
What You Must Submit
Approach
(Due Oct 21, 23:59)
- Approach PDF (3-5 pages): problem framing; method (how ontology + AI/LLMs are used); system diagram; safety/privacy; feasibility & build plan.
- Worked examples (≥3) with explicit reasoning paths (which classes/relations/filters).
- Prompts / Pseudocode / Rules / DSL (enough to reproduce the reasoning).
- Repo link (optional now; required if you become a finalist).
- Short video (optional, ≤3 min).
Build (Finalists Only)
(Due Oct 27, 23:59)
- Private repository (not public): grant read access to organizers/judges; include a README, setup/run steps, and license/attribution for any third-party components.
- Runnable demo/notebook and evaluation results on the provided datasets.
- Video demo (5-7 min) and one-pager (problem, method, results).
- Any additional items specified in the finalist brief.
- Offline run proof: Provide setup steps (env/Docker) and local model artifacts (weights, indexes/embeddings) so the demo runs with egress blocked.
- No external services: Your code must not call hosted LLMs, SaaS vector DBs, or third-party inference APIs during evaluation.
- Submit early; late entries cannot be accepted.
Use Of Data, Models, And Tools
- Ontology & seed data:
Provided in the Resources; treat seed data as synthetic and minimal. Finalists may receive extended data for evaluation.
- No sensitive data:
Do not include personal data, or confidential third-party content in any submission.
- LLMs & AI tools (Air-gapped required):
Submissions used for judging must run locally/offline. No public LLMs and no internet-dependent services (e.g., OpenAI/Anthropic APIs, hosted vector DBs, telemetry). Package models and indexes with your submission (or provide a local download step we can run before the network is blocked). Allowed local runtimes include PyTorch/TensorFlow/JAX, llama.cpp/vLLM/Ollama, spaCy, local graph/SQL stores, and on-box vector search.
- Development time:
You may prototype with hosted tools only if your finalist build ships an equivalent offline path. Approaches that cannot be made local may be deemed ineligible.
- Network policy & audit
Finalist repos are evaluated with network egress disabled. Solutions that attempt outbound requests may be disqualified.
- Third-party content & code
You are responsible for licenses/permissions. Use only licenses that allow OPTIMAS to use, modify, and commercialize the submission (e.g., MIT/Apache-2.0/BSD). Avoid GPL/AGPL unless explicitly approved in writing.
- Generalization
No brittle hard-coding of instance IDs. Methods should generalize across seed and extended datasets.
- Reproducibility
Provide prompts/templates/rules or pseudo-code so judges can simulate Phase-1 reasoning. Note any randomness and how seeds are fixed.

Intellectual Property (IP) - OPTIMAS Ownership
- 1. Ownership of Submissions All submissions, code, designs, models, documentation, and other materials developed by participants during the Hackathon ('Submissions') are and shall remain the exclusive property of Optimas.ai Inc.
As a condition of entry, participants hereby assign all rights, title, and interest in Submissions to Optimas.ai, including all intellectual property rights worldwide. - 2. Background & third-party components: You retain ownership of Background IP and any third-party components you lawfully use. Identify all such components (name, version, license, URL) and ensure their licenses permit OPTIMAS&aspo;s intended use under the license above. Avoid GPL/AGPL unless you understand and accept those terms or have written approval from OPTIMAS
- 3. No confidential data Do not include personal/sensitive data, or content you lack rights to disclose.
- 4. Publicity release: You allow OPTIMAS to use your team name, and project title/description in winner lists, blogs, social posts, and event materials. You may likewise reference your participation and link to any materials OPTIMAS makes public.
- 5. Paperwork: Finalists may be asked to sign a short confirmation of the above license and third-party disclosures before prize payment
Privacy & Data Handling
- 1. We collect basic registration/submission info to run the event (contact, team, links/files).
- 2. We do not request personal/sensitive data in your content. If included by mistake, we may delete/redact it.
- 3. We may store submission metadata for judging and audit. See the site's Privacy Policy for details and contact for data requests.
Approach Phase Criteria
- 1. A panel of researchers/practitioners will review submissions. Judges may request minor clarifications (no new material).
- 2. Ties: Broken by higher Ontology reasoning rigor, then AI/LLM & safety, then Feasibility.
- 3.Decisions are final.

Prizes & Payments
- Finalist Awards: 5 x US$1,000 per track (selected from Approach submissions; 15 total)
- Grand Prize: US$10,000 per track (awarded after the Build phase; 3 total).
- Who gets paid: Prizes are per winning team (not per person). If you register as a solo participant, you are a team of one and receive 100% of the prize (subject to taxes/fees).
- Payout logistics: For multi-member teams, the prize is paid in one transfer to the team's designated/admin payee; the team is responsible for any internal split. OPTIMAS will not mediate team-split disputes.
- KYC/Tax: Winners must complete reasonable identity/eligibility checks and any required tax forms (e.g., W-9/W-8BEN).
- Timing & method: Typically within 30 days of winner verification and signed paperwork, via bank transfer or an agreed digital method. Transfer fees/withholding taxes may be deducted as required by law.
- If unreachable/ineligible: If a team is ineligible or cannot be reached within a reasonable period (e.g., 14 days), the organizer may select an alternate.
Code Of Conduct
