Since Charity Navigator prominently displays a charity’s star rating which is assigned based on its overall rating, one can identify the causal impact of a one star increase ...
متن کاملGenerating bracelets with fixed content
We present an algorithm to generate bracelets with fixed content. An analysis shows that the algorithm runs in constant amortized time. The algorithm can be applied to efficiently list all non-isomorphic unicyclic graphs with n vertices.
