Abstract
Historically, approximate pattern matching has mainly
focused at coping with errors in the data, while the or-

correct, while the locations may have shifted/changed.
We formally define a broad class of problems of this
type, capturing situations in which the pattern is ob-

We consider several natural rearrangement schemes, in-
