I guess that every np-complete problem reduces to the np-hard problem, so the given statement is true. But don't know how to prove it.

1Halting problem is not NP-hard. It is unsolvable.user58697– user586972020年07月29日 18:53:58 +00:00Commented Jul 29, 2020 at 18:53

Every problem in NP reduces to every NP-hard problem, and a problem is NP-complete if it's in NP and it's NP-hard. You don't prove those things. Those are the definitions of NP-complete and NP-hard. You could reduce every NP-complete problem to halting, but why?Matt Timmermans– Matt Timmermans2020年07月29日 19:51:08 +00:00Commented Jul 29, 2020 at 19:51
