I have proposed an algorithm for a scheduling problem in a submitting paper. In the revision, the reviewer asked us to compare with another algorithm in the literature. Our algorithm is in MATLAB, and the comparing one is in C++, and the code is publicly available. We did not re-implement the C++ code, to avoid any decrease in the efficiency of their algorithm, and to save time as well. Now the reviewer is responding: ``It is probable that there is a significantcant difference in performance between MATLAB and C++. The authors should make it clear if and how the results were normalized to ensure a fair comparison.''
So my question is this: Is there any (scientific) ratio or similar comparison between the efficiency of MATLAB and C++?
When we opted to use the available code, we thought it is completely OK since MATLAB is known to be slower. So using the comparing algorithm in a faster environment is OK. I should add that our algorithm is now performing much better than the comparing one.
