In computational physics, the vast majority of papers has the following structureThey propose some new algorithm, or improvement to an existing oneThey give numerical examples, ideally comparing relevant characteristics of their new method with existing methodsI am wondering which journals would publish a theoretical analysis of an existing algorithm, e.g. Algorithm X was previously hypothesized to have stability condition Y (but this was not proven), and this is indeed true because (math proof). Such a paper would deviate from the structure above in that it neither proposes a new algorithm, nor provides numerical examples. It merely proves that an existing algorithm has certain characteristics.
