I am studying about incremental programming of restricted (low power) IoT devices and discovered that many diff algorithms have been introduced by the literature (DASA, R3DIFF, DG, etc).
Trying them out, I found out that xdelta generally produces smaller patches. Hence the evident question is the following: Is xdelta suitable for such an environment and If yes, why do you believe the authors did not simply use xdelta algorithm for their applicationws (and instead developed other diff algorithms)?
