(definition)
Definition: In a linked structure, replacing a pointer with the pointer it points to. Used for various algorithms on lists and trees.
Also known as recursive doubling, shortcutting.
Note:
The name "recursive doubling" comes the fact that if all the pointers are jumped at every step, the pointers cover double the distance with each recursion.
