Key ideas in The Hidden Geometry of Your World
- Always extend the path that currently has the lowest total time from the start
- Checking the shortest known connection first prevents missing a shortcut
- A small delay can make an alternative branch of the network suddenly faster
- The 'best' path depends on the relative cost of all connected options
- Systematic pathfinding
- Network sensitivity
- Calculate the new total time using the shortcut
- Why a single change in a network can invalidate the entire current best route
- Compare the new total to the previously recorded 'best' time
- Update the route map only if the new total is lower
- The sequence of updating path values as new information is discovered
- The person cutting must create two shares they value exactly the same.
- Fairness is based on what each individual person values most.
- The person not cutting gets to pick their favorite piece first.
- Identical slices can have different values if the contents aren't uniform.
- Applying the 'divider-chooser' method to ensure fairness
