## How to rank pages on the web

### Game

The goal of this game is to find a configuration of the links between of some web pages which leads to given values for PageRank for each page. Note that there might exist several solutions, all of them defining a configuration compatible with the given PageRank values. To choose the links that you want to include in the game, you should proceed in the same way as described for the applets (see "Applets"), although here you can not choose the number of pages nor the value for $$p$$ (taken equal to $$0,85$$). The game has 15 levels corresponding to different difficulties. The first levels are, as expected, the easiest ones involving a small number of web pages. After the successful completion of a level, you will be asked if you want to continue for the next level, until all the 15 levels are completed. If you find it too difficult, you may use a little "help", that will inform you of you are progressing towards a solution of the present level...
