How efficient is your clone? Evaluating LLM capabilities for runtime and memory-aware code selection
DOI:10.1016/j.jss.2026.112973.png)
Abstract
En 中文
• Execution-free evaluation on CodeNet and CLBG across Python, Java, and C. • Code+feature prompts lift decoder LLMs more than encoder baselines. • LoRA yields selective gains; language–aspect effects remain context-dependent. • Top-1, MRR, and eGap reveal trade-offs beyond often-saturated Top-3.
