Recursion and Divide-and-Conquer
2 notes move from the word to a real choice at work — understand it first, then decide whether to use it.
Each note stands alone, or becomes the next step in this thread.
THE QUESTION THIS PAGE ANSWERS
ANSWER FIRSTWhat is Recursion and Divide-and-Conquer, and which AI decisions does it change?
Walk a directory tree, break down tasks, draw a fractal tree—same playbook: call yourself. Watch an Agent recursively split “build a site” into actionable small jobs This page keeps the related concepts, common mistakes, and practical notes in one reading thread.
First decide whether you are blocked by a definition, a choice, or verification; then choose the closest of the 2 notes below.
Start with “Recursion: Break a Big Job into the Same Smaller Job,” then restate the conclusion using your own task.
Do not treat every method in a topic as interchangeable. The answer changes with the input, risk, and acceptance bar.

Put the word back inside the choice it changes.
Recursion: Break a Big Job into the Same Smaller Job
Walk a directory tree, break down tasks, draw a fractal tree—same playbook: call yourself. Watch an Agent recursively split “build a site” into actionable small jobs
Divide and Conquer: The Algorithm Behind Context Compression
Compaction in the AI Practicum is really divide and conquer: split a long chat, summarize each chunk, then merge. Run recursive summarization yourself and watch information compress layer by layer
