A while back, FoxGlove Sec wrote up an article about fuzzing. In it, they mentioned that at some point during fuzzing you need to minimize the test cases again, then re-seed. Is this still the case or does AFL handle all of this during its normal course of execution?

de-duplication and size reduction. It's not as thorough as afl-cmin or
afl-tmin (and not as definite), but it's good enough for most uses.
