Computer Science / Unit 3 CS 0120 short lesson, about 20 seconds
The Problem Model
Captions available
The idea
A problem model is a simplified, abstract representation of a real-world problem — it emphasizes the details judged relevant and erases the rest so an algorithm can operate at all.
In practice
A medical system models patients as age, weight, and vitals — not their politics or stories.
Where people slip
What a model erases was somebody's judgment call.
