An Improvement of the Biased-PPSZ Algorithm for the 3SAT Problem
Osamu Watanabe, Tong Qin (Tokyo Tech) COMP2021-2
Abstract (in Japanese) (See Japanese page) 
(in English) Hansen, Kaplan, Zamir and Zwick (STOC 2019) introduced a systematic way to use ``bias''
for predicting an assignment to a Boolean variable in the process of PPSZ and showed that
their biased PPSZ algorithm achieves a relatively large success probability improvement
of PPSZ for Unique 3SAT. We propose an additional way to use ``bias'' and show by numerical analysis that the improvement gets increased further.
