Lecture 10 - Oct. 17

Tournament:
Mapper will be appointed. Randomly pick from multiple models and mix (pick of 4-8 mappers).
Guesser:
n, the length of the mapping: 2, 3, 5, 10, 20, 100, 1000, 10^4, primes, 10 repetition. 1 cpu second per guess.
penalty of the making wrong guess

Bug: query the same till cut off, but get score of 0.

Mapper: part of the mapping binary and the rest not.

For binary mapping, should narrow down gradually or jump to pair query after a couple of big group query. For narrowing down strategy, the decision tree grows exponentionally.

Grid query. Try never query two numbers together more than once.

Wednesday lecture new place at the open meeting room.
