Given a particular idea, is there any scientific word, or an elegant way to describe in once sentence, that I am pretty sure there is no method not based on this particular idea? For example, when writing a scientific paper, I am pretty sure I read every paper on the topic, and there is no mention of any other idea for a method, how would I then write:
All methods to date are probably based on idea xyz.
or
To the best of knowledge, all methods to date are based on idea xyz.
I find above sentences to sound like I didn't have the motivation to search long enough or just didn't care.
