Recommended system complementary strategies and algorithms
algorithm can be done globally ordered, but the number of bits recommend a brush is fixed, finite, then how to ensure diversity among the contents of a brush it? Start sorting the results in order to single out a number can represent one or several dimensions (in descending several dimensions) elements, and then follow the beaten rules (such as different authors separated from each other) break the rules. Sorting algorithm can solve the problem, as a complement, diversity and scattered policy can do something beautiful on the richness of the experience and to show the order on the basis of
A better solution is: What algorithm is also considered a good style of the article and the proportion of each type of article, a brush should be placed in each location;
