Abstract
A sufficient condition for the equality of the plausibility and
commonality measures of the Dempster-Shafer belief calculus is
developed. When the condition is met, an efficient method to calculate
relative plausibility is available. In particular, the method can be
used to calculate the relative plausibility of atomic hypotheses and,
therefore, it can be used to find the choice that maximizes this
measure. The computation is efficient enough to make Dempster-Shafer
practical in some domains where computational complexity would otherwise
discourage its use
