Erdős problem 349

For 0<α10 < \alpha \le 1 and any t>0t > 0, (t,α)(t, \alpha) is not a good pair: every term tαn\lfloor t\alpha^n\rfloor lies in the finite interval [0,t][0, \lfloor t\rfloor] (since αn1\alpha^n \le 1), so every subset sum is bounded by the constant i[0,t]i\sum_{i \in [0,\lfloor t\rfloor]} i, and no large integer can be a subset sum. A partial result on the open Erdős Problem 349, complementing the 2<α2 < \alpha and integer-coefficient cases.

For what values of t,α(0,)t,\alpha \in (0,\infty) is the sequence tαn\lfloor t\alpha^n\rfloor complete (that is, all sufficiently large integers are the sum of distinct integers of the form tαn\lfloor t\alpha^n\rfloor)?
