PriceTape
The machine agrees with itself tonight
PriceTape’s nightly step was run 20 more times under other random seeds. The share of the book it would hold ranged from 0% to 17%, with a median of 17%. Here is what that spread looks like, and what the machine’s survivors have done since its public record began.
The routes it could have taken
The survivors
Every one of the 56 programs alive tonight, run over the live record. Shaded: the middle half and the middle 80% of the population. Is the champion typical of what the machine believes, or an outlier?
How sure is tonight’s decision?
Tonight’s step rerun 20 times under other random seeds. Each dot is the share of the book one rerun would hold; the ring is the decision actually taken. A tight cluster means the decision is the machine’s. A wide spread means it is the luck of the draw.
