In NOV 1999,http:/www. slashdot.org released an online poll asking which was the best graduate school in Computer Science. As is the case with online polls, the IP addresses of voters were recorded in order to prevent single users from voting more than once. However, students at Carnegie Mellon University (CMU) found a way to cast ballots using programs that voted for CMU thousands of times. CMU’s score started growing rapidly. The next day, students at the Massachusetts Institute of Technology (MIT) wrote their own program and the poll become a contest between software robots. MIT finished with 21,156 votes while CMU finished with 21,032 votes. Others got less than 1,000.

Question
