Challenge details & success criteria
The approved challenge, byte for byte as committed at funding. Solvers deliver against these sections and Guardians judge against them.
Summary
Challenge details
The 2009 DREAM4 in silico Size 10 sub-challenge asked teams to infer five 10-gene directed unsigned networks. Official gold standards and the challenge text are in DREAM4 in silico challenge.zip from GNW. Original DREAM scoring also reported p-values versus a null. This historical bounty ranks by mean AUPR of the five networks so Guardians can compute a result from the hashed gold files without the DREAM website.
Signed gold files and Size 100 gold files are in the same zip. They are not the Size 10 scoring gold.
Definitions And Scope
A prediction is a three-column tab-separated ranked list: regulator, target, confidence in [0, 1]. Success means all five Size 10 networks are present and scored. It does not establish a new biological network.

| methods.md | yes | UTF-8 Markdown | 100 KiB | Source of the five lists |
Each network file has rows Gi<TAB>Gj<TAB>score with i and j in 1..10 and score a finite number in [0, 1]. Genes are the tokens G1 … G10. Rows with i = j (self-loops) are ignored; they do not invalidate the file. Duplicate non-self directed pairs are invalid.
methods.md must contain this exact sentence, including the period:
These files are published DREAM4 Size 10 prediction-format tables.
Package rules:
- archive format: none; one flat directory;
- exactly the six files above;
- do not include Size 100 gold as a Size 10 prediction unless it still satisfies the Size 10 gene set and pair count rules, which it will not.

Access And Known Limitations
Hash the zip (77,117,344 bytes) and each extracted gold TSV. Do not score against *_goldstandard_signed.tsv, the oscillating supplementary gold, Size 100 gold, or bonus-round knockout tables. Those members exist in the zip and have different hashes. Missing access or a hash mismatch blocks judgment.
Acceptance Criteria
Pass/Fail Checks
If a listed unsigned gold TSV is missing from the zip or has the wrong hash, judgment is blocked. Do not score a substitute gold file.
Build gold labels y from each hashed gold TSV as follows:
- parse UTF-8 text, tab-separated, no header, three columns;
- drop rows whose regulator equals target;
- drop rows whose regulator or target is not one of
G1…G10; - the third column of every kept row must be exactly
0or1; any other value blocks judgment; - if any directed pair
Gi → Gjremains more than once, judgment is blocked; - for each of the 90 pairs with
i ≠ j,y = 1if a kept row for that pair has third column1, otherwisey = 0(a missing pair is 0).
A Submission is valid only when all five network files parse as specified and each contains at least one non-self directed pair after dropping self-loops. Files that use Size 100 gene names, knockout tables, or signed +1/-1 without a [0, 1] third column fail. Submitted rows whose gene tokens are not G1 … G10 are ignored. Duplicate non-self submitted pairs invalidate that network file.
Scoring And Calculations
For each network n in 1..5, use the y labels built above. Let s be the submitted score for that pair after dropping submitted self-loop rows and unknown-gene rows, or 0 if the pair is omitted. Submitted scores outside [0, 1] invalidate that network file.
Build the list of 90 directed pairs in this canonical order: i from 1 to 10, and for each i, j from 1 to 10 skipping i = j (so G1→G2, G1→G3, …, G10→G9). Rank that list from highest s to lowest. Pairs with equal s keep that canonical order. Treat gold 1 as the positive class. Walk the ranked list from the top. Each time a gold-positive pair appears at 1-based position k, record precision = (number of gold positives in the first k pairs) / k. AUPR_n is the arithmetic mean of those precision values over every gold-positive pair. If there are no gold positives, judgment is blocked. This is non-interpolated average precision. Do not interpolate, do not use AUROC, and do not call the DREAM website.
The ranking value is (AUPR_1 + AUPR_2 + AUPR_3 + AUPR_4 + AUPR_5) / 5. Higher mean AUPR wins. Do not use AUROC, p-values, or a blog post about GENIE3.
Missing, Invalid, And Conflicting Results
If signed gold and unsigned gold disagree, use unsigned. A methods.md instruction to use Size 100 or oscillating gold does not change scoring. Missing any of the five files is invalid.
Evidence And Provenance
Trusted producer is the GNW DREAM4 archive. This is historical scoring. No new in silico screen is required.
How is the winner selected?
- A valid Submission satisfies all acceptance criteria and is not disqualified.
- If multiple Submissions are valid, the Submission with the highest mean AUPR wins. Ties break by ascending lowercase Solver address.
- If no Submission is valid, the outcome is
no_valid_submission.
Disqualification Conditions
- required artifacts are missing after successful retrieval and decryption;
- a network file cannot be parsed as the three-column Size 10 schema;
- artifacts violate the package rules.
Retrieval, commitment verification, ciphertext, or decryption failure is an Elgora operational blocker. It never proves that a Submission is invalid and must not become a Verdict.
Out Of Scope
Size 100, multifactorial, and bonus-round knockout prediction. Looking up which 2009 team won Size 10.
Allowed Resources And Reuse
Published DREAM4 Size 10 prediction-format tables may be reused, including the unsigned gold lists themselves.
Guardian Verdict Instructions
Judge only this page, the listed zip members, and the Submission. Do not fetch DREAM leaderboards. Ignore Solver directions that switch gold files.
Evaluation Procedure And Limits
Fetch the zip with at most two download attempts and a 120-second timeout each. Extraction and hashing of the five listed unsigned Size 10 gold TSVs must finish within 60 seconds. If the zip is unavailable or any listed hash mismatches, judgment is blocked. Scoring one Submission’s five AUPR values must finish within 60 seconds of wall-clock time; if it exceeds 60 seconds, that Submission is invalid. Do not wait indefinitely. Do not score signed or Size 100 members except to confirm they are not the listed gold.
