Suppose I found out an algorithm/theorem, which is easy to understand and may be easy for the experts in the field to get it (with either same or different language). But after literature survey, If I strongly came to know that it is not yet published anywhere. Can I send my paper to the reputed journal for reviewing?
In concise, my doubt is whether the novelty of a research paper refers to the novelty with respect to the existing literature or has to be completely new in that field such that hard to reach it.
