Has the same relation to E as BPP does to P.
EE = BPE if and only if EXP = BPP [IKW01].
Equals DTIME(22O(n)) (though some authors alternatively define it as being equal to DTIME(2O(2n))).
EE = BPE if and only if EXP = BPP [IKW01].
Equals DTIME(222O(n)).
In contrast to the case of EE, it is not known whether EEE = BPEE implies EE = BPE [IKW01].
