Fiddler answer: 1 team can never win (the 2-seed)
Extra Credit: 27 teams never win
Explanation:
This is part 2 of the March Madness (or should I say "Mathness") Fiddler. Unlike last week, this week, we are exploring how often underdogs win given any boost B. For the original puzzle, let's think critically.
For the 4-seed to win out, it needs to beat the 1-seed in the first round, which can be achieved with \(B > 3\). This boost \(B\) will be sufficient to beat out the winner of the 2-3 matchup, since both of them will not receive any boosts when facing the 4-seed, and the 4-seed's boost of \(B > 3\) is sufficient to beat any opponent.
On the other hand, for the 1-seed to win out, it needs to have \(B < 1\). In this case, even the 2-seed cannot beat the 1-seed with similar analysis as above.
When \(1 < B < 2\), the 3-seed will emerge victorious against the 2-seed, but will fall at the hands of the 1-seed who will advance against the 4-seed. When \(2 < B < 3\), the 3-seed will once again be victorious against the 2-seed and in fact will win the entire tournament. In any case, the 2-seed will never win the tournament for any value of B (non-integer as given).
Therefore, the answer to the original Fidder is that one team never wins: the 2-seed.
I wrote a MATLAB script to generate the desired bracket, calculate the eventual winner given any value of \(B\), and visually present it in a GIF for values of \(B\) going from 0.5 to 63.5 in increments of 1.
From the above animation, 27 teams never won. When the boost value \(B\) reaches a critical value of \(B > 32\), it will steadily give seeds 48 and above the victory. For boost values less than 32, there are flunctuations in the lower-seeded teams and the higher-seeded teams don't have enough boost to win out.
Below is the complete list of winners for each boost value from 0.5 to 63.5. For values less than 1, the 1-seed always wins. For values greater than 63, the 64-seed always wins.
