What is "salami slicing"? Does it preclude presenting similar papers on a similar topic at multiple conferences?
Salami slicing normally refers to a different practice; that of taking a result and slicing it up into several smaller results with the intent of getting multiple publications. Technically all of the resulting papers are different, but less significant than if all were presented together in a single paper (or smaller number of papers).
It doesn't really have to do with &quot;similarity&quot; as such. But some conferences would frown on &quot;virtually the same&quot; paper at their conference.
But it depends. If the purpose of a conference is simply to broaden the audience of a result then there may be no issue. But conferences in some fields, such as CS, are primary publication venues and the proceedings have the same weight (or more) than journal publication.
In the latter case you have issues about self plagiarism and multiple publication, both of which are best avoided.
But I know some people who give similar talks at multiple conferences (often by invitation) and there is no issue, since their talk isn't intended to represent new results. So, a bit subtle, depending on the conference.
So, while your idea may not be technically &quot;salami slicing&quot; you still need to evaluate its appropriateness.
