What are examples of non-oracular versions of famous oracular problems?

Most quantum algorithms proposed, including Deutsch-Jozsa, Simon's, Bernstein-Vazirani etc, involve querying an oracle. If I understand correctly, the speedups depend on the oracle being efficiently ...

Deutsch-Jozsa algorithm as a generalization of Bernstein-Vazirani

It is known that both algorithms use the same gates: $H^{\oplus n}U_fH^{\oplus n}$. After the circuit, the qubits are in the state $\sum_y \left( \sum_x (-1)^{f(x)+xy} \right) |y\rangle $. In DJ's ...

Is the Bernstein-Vazirani algorithm dependent on the specific behavior of the oracle?

My understanding of the Bernstein-Vazirani algorithm is as follows: We have a black box oracle with secret string $s$. The black box does $$f(x) =s\cdot{x}=(\sum_1^n s_i\cdot{x_i})$$ We run each ...
