How do ur guys retrieve the edge cov?

[PoShaung]

Hi! I personally have another concern about how ur guys retrieve edge coverage of the target program. I have tried the afl-plot and afl-showmap (both from AFL tool set to get edge coverage) to retrieve the edge coverage results, however, the result seems have some gaps to the original paper(while afl-showmap too large and afl-plot too small). On the contrary, I have found that I got the closing result by analysing the afl-showmap result which ignoring the visit times information, i.e., (edgeA:2) and (edgeA: 4) are considered as the same edge, which is "edgeA" here.

Is this ur way to collect the edge coverage? If not, what is ur approach to collect edge coverage? Thanks for your time and looking forward to your reply!
