Consider a scenario where one (say Mr. X) has implemented a method for solving a problem, experimented it on a dataset D and obtained significant results. The obtained results seem to be better than a set of results published in a paper P in a reputable journal J which solves the same problem experimented on D by some another author.
Mr. X decides to cite P and directly compare the claimed results published in it with his own.
The question is how much necessary (in the perspective of a reviewer) is it for Mr. X to reproduce the results published in P by himself if he is to publish in
- a) the same publisher as journal J?
- b) a totally different journal publisher?
Most importantly, what would be the case if J is an IEEE journal?
