CodeWalk — Clone Equivalence
Decide whether two composite Java programs are semantically equivalent. A level-N
task chains N method pairs on each side; the composition is equivalent only if every
constituent pair is equivalent, and not_equivalent when exactly one non-equivalent pair is
injected. Part of the CodeWalk benchmark suite.
- 100 tasks per level for L1–L3, balanced 50
equivalent/ 50not_equivalent. - Single-call classification task (no tool access): the model reads both programs and emits one verdict.
Note on splits. These are the balanced 100-per-level sample sets. The accompanying paper reports results on its held-out evaluation splits (86 / 82 / 84 / 166 tasks at N = 1/2/3/10); confirm which split you intend to publish as canonical before release. L10 is not included in this package.
