ES Heterogeneity Countdown
Countdown arithmetic data used for Evolution Strategies experiments under
heterogeneous data allocation.
Dataset splits
train: approximately 3.79 million synthetically generated, solvable, and
deduplicated Countdown problems.
test: 2,000 held-out Countdown problems from the original evaluation set.
Each example contains:
id: example identifier
numbers: input numbers that must each be used exactly once
target: desired arithmetic result… See the full description on the dataset page: https://huggingface.co/datasets/es-heterogeneity/countdown-dataset.countdown-rlvr

Countdown Qwen3-0.6B Pass@10 Buckets
Countdown arithmetic problems filtered by observed local Qwen/Qwen3-0.6B success rate over 10 rollouts per problem.
Each problem asks for an arithmetic expression that reaches a target using each listed source number at most once. The final answer should be inside \boxed{...}. Canonical solutions are provided, but any verifier-valid expression is accepted.

Countdown multiplication SFT dataset
About 5,000 Countdown problems that genuinely require a multiply or divide (no add/sub-only
solution exists), each paired with a correct, worked solution from a brute-force solver. Used to
supervised-fine-tune Qwen2.5-3B in the
GRPO/SFT Countdown study.
Each row is a prompt / completion pair in the chat format the model trains on. The completion
reasons inside <think> </think> and gives the final equation inside <answer> </answer>:
