# Ruby

**Objective:**

Ruby uses program dependency graph (PDG) analysis to evaluate code structure similarity. It compares the logical structure and dependencies of generated code with a reference, identifying structural and semantic alignment, making it well-suited for complex programming tasks where accuracy in logic flow is crucial.

**Required Columns in Dataset:**

`Generated Code`, `Reference Code`

**Interpretation:**

* **High Ruby Score:** Suggests that the generated code aligns closely with the logical structure of the reference code.
* **Low Ruby Score:** Indicates deviations in code logic or structure, potentially affecting functionality.

**Execution via UI:**
