Constructor Detail

CatCmp

public CatCmp(HashMap<String,OnlineSectProof.Counter> countCat,
              HashMap<String,OnlineSectProof.Counter> totalCat,
              HashMap<String,Integer> worstCaseCat)

Constructor

Parameters:

countCat - table (category, number of sequences of that category)

totalCat - table (category, total number of students that were not sectioned of a sequence from this category)

worstCaseCat - (category, worst number of students that were not sectioned of a sequence from this category)

Method Detail

compare

public int compare(String c1,
                   String c2)

Higher number of not-sectioned students in the worst case goes first. If the same, higher average number of not-sectioned students goes first. If the same, compare by category.
