Do all accelerated failure time models satisfy the proportional hazards assumption?

Suppose we are given  chess players participating in a chess tournament, and suppose for the sake of simplicity that  is a power of 2. The tournament goes through several rounds, where, in the first round, all players are participating in some chess game, and only the winners of round 1 move on to round 2 where they are paired again and conduct new games. The winners of round 2 move onto round 3, and so on until only two players remain for one final game. Thus, in each round, half the participants are eliminated until there is one left. We wish to determine who the best player is and who the second best player is. The best player  is the player who loses no games. The second best player  is among the players who only lose a single game (to the best player). (i) Determine a tight asymptotic bound on the number of chess games necessary to determine the best player . For each option, select if it is true or false. 1)

Please read each option and follow the instructions while being recorded during your proctoring session.  I used scratch paper during the exam. I have destroyed it in a manner that it cannot be used by another in any form to gain an advantage on the exam. I used a whiteboard during the exam. I have erased all markings so it cannot be used by another in any form to gain an advantage on the exam. I used a combination of scratch paper and a whiteboard during the exam. I have destroyed the scratch paper and erased all whiteboard markings so neither can be used by another in any form to gain an advantage on the exam. I did not use scratch paper, a whiteboard, or a combination of scratch paper and a whiteboard during the exam because those items were not permitted on my exam allowances or I chose personally not to use them.
