Discussion
Why is the repeated work of iterative deepening acceptable?
Answer: C
In a tree with branching factor b, the bottom level holds more nodes than all the levels above it combined, so regenerating the upper levels adds only a constant factor of about b over b minus one. For a branching factor of ten that is eleven per cent. Nothing is remembered between iterations, and no pruning occurs. An overhead that appears alarming until the exponential is examined is a good illustration of why complexity arguments must be done rather than estimated.
