Minor inconsistency in gradient descent #97

Closed Luc-Veldhuis closed 4 years ago

Luc-Veldhuis commented 4 years ago

At line https://github.com/AngoraFuzzer/Angora/blob/master/fuzzer/src/search/gd.rs#L219 there is a check for linearity if f_minus != f0 however, when f_minus < f0 is true, this check is still there: https://github.com/AngoraFuzzer/Angora/blob/master/fuzzer/src/search/gd.rs#L224

I opened a PR here: https://github.com/AngoraFuzzer/Angora/pull/96
