What I mean by this is there are already good heuristics which work very well and finding an hard instance is tough. So if $3SAT$ reduces to $GI$ then most cases of $3SAT$ are easy except a few rare instances?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-16324801549838227402015-11-12T20:37:17.128-06:002015-11-12T20:37:17.128-06:00FYI.

It was in RP \cap co-RP but AFAIK the best known deterministic algorithm was still exponential. Is that not accurate?D. Sivakumarhttps://www.blogger.com/profile/05750992965116762335noreply@blogger.com
