Strategies Are Purchases
Captions available
The idea
Choosing a search strategy is a purchase: a guarantee is bought and a cost is paid — fewest-steps for memory, thrift for risk.
In practice
Breadth-first: a guarantee, an exponential frontier. Depth-first: a light frontier, ordering roulette.
Where people slip
"Which is smarter?" is the wrong question; "what does it guarantee, at what price?" is the reading habit.
