Exam-style question
Try this first
Explain what is meant by problem abstraction. In your answer, describe what happens to the details of the original problem and why this is done.
Model answer
What a good answer should say
- Problem abstraction is the removal of details from a problem until it is represented in a form that is possible to solve.
- Details that are not needed for solving the problem are omitted, while the relevant information is retained.
- This makes the problem simpler to represent and work with.
Explanation
Why this works
A complete answer must state that details are removed and explain that this continues until the problem has a representation that can be solved. It should not suggest that every detail is removed.
