Reduction from CNF-SAT to Positive Betweenness Centrality

FROM: CNF-SAT TO: Positive Betweenness Centrality

Description

Positive Betweenness Centrality in directed or undirected graphs with weights in $\{1, 2\}$

Implications

if: to-time: $O(m^{2-\epsilon})$ for some $\epsilon > {0}$
then: from-time: $O*({2}^{({1}-\delta)n})$ for some $\delta > {0}$
