[PATCH] D100161: Redistribute energy for Corpus

gtt1995 added a comment. I redesigned the algorithm and did a complete long-term evaluation by myself, and got very good results. Whether it is -entropic=0 or 1, it performs very well, and -fork mode is now better than paralllel fuzzing mode Better performance, please move to D105084. Th

morehouse added a comment. At this point I am not convinced this patch will provide benefit for the default use case when `-entropic=1`. I am hesitant to add complexity to the code for unsure benefit. If you request a FuzzBench experiment
