On the multiobjective repair algorithm in Arja(-e)

[DehengYang]

Dear Sir,

Sorry for interrupting you here. I notice that both tools employ multi-objective genetic programming (MOGA) as the core repair algorithm for patch generation, where the first objective is the patch size, and the second is failure rate. Here I would like to ask a question: Would minimal patch size sacrifice the effectiveness of Arja and Arja-e? I am currently exploring next step of APR, during which I observed that many bugs in Defects4J, multi-hunk bugs in particular, always requires multiple edits. Therefore, if the patch size is limited, it might limit the ability of Arja(-e) to generate multi-edit patches according. Thus, I have such a doubt which I would like to present for your further guidance. It would be sincerely appreciated if any advice could be offered. Thank you!
