some selection scheme is used to reduce the number of papers under
consideration: If the papers are rank-ordered, then the bottom 30% that each
judge rank-orders could be rejected. Alternatively, if the judges do not
rank-order, but instead give them numerical score (say, from 1 to 100),
then all papers below some cut-off level could be rejected.
The new pool of papers is then passed back to the judges, and the process is
repeated. A concern is then the total number of papers that judge reads must be
substantially less than P. The process is stopped when there are only W papers
left. There are the winners. Typically for P=100, W=3.
Your task is to determine a selection scheme, using a combination of
rank-ordering, numerical scoring, and other methods, by which the final W
papers will include only papers from among the "best" 2W papers. (By "best",
we assume that there is an absolute rank-ordering to which all judges would
agree.) For example, the top three papers. Among all such methods, the one that
