The PPSZ Algorithm presented by Paturi, Pudlak, Saks, and Zane in 1998 has the nice feature that the only satisfying solution of a uniquely satisfiable 3-SAT formula can be found in expected running time at most $\mathcal{O}(1.3071^n)$. Using the technique of limited independence, we can derandomize this algorithm yielding $\mathcal{O}(1.3071^n)$ deterministic running time at most.
