Grid and sequence DP

Understand Grid and sequence DP

Start by naming the decision behind Grid and sequence DP. A strong answer explains the goal, the constraints, and the evidence you would use before acting. Do not treat a checklist as understanding: connect each step to the outcome it protects.

Practise with evidence

Create one small example for Grid and sequence DP. Write down your assumption, the action you take, and the observable result. If you cannot explain why the result matters, reduce the example and try again.

A useful comparison

Think of Grid and sequence DP like planning a journey: a destination without a route is only a wish, while a route without a destination wastes effort.

Check the decision, not just the terminology.

Quick check: What is the most useful way to apply Grid and sequence DP?

• State the goal, constraints and evidence before choosing an action.
• Copy a template without checking whether it fits.
• Use the most complex option first.
