2 Problem-Solving Strategies Online Quiz Questions

True

False

Use a heuristic to guide the search with a practical rule of thumb.

Follow an algorithm that gives a defined sequence of steps.

Use analogy by adapting a solution from a structurally similar problem.

Use trial and error by testing possible actions and learning from the results.

Change one relevant factor at a time.

Repeat a failed attempt without changing anything or recording its outcome.

Record what was tried.

Test several unrelated changes at once so the cause of an outcome remains unclear.

Use each outcome as information for the next attempt.

Use an algorithm because a fixed sequence is known to solve every new problem.

Use a heuristic because any surface resemblance makes the previous solution reliable.

Use analogy, while checking that the important constraints match.

Use trial and error by repeating the previous solution without considering the new problem.

Use an algorithm, since an exhaustive defined procedure is always practical when time is limited.

Use a heuristic to guide the search, then check the result because the rule of thumb may fail.

Use analogy without checking constraints, since a similar-looking problem guarantees a matching solution.

Use trial and error by repeating attempts without recording them.

Identify the starting state.

List unrelated background details even when they do not affect the problem.

Specify the goal.

Identify relevant constraints and possible actions.

Record every available detail, whether or not it affects the goal or available actions.

Identify the starting state, goal, relevant constraints, and possible actions.

Choose an action first and define the goal afterward.

Ignore constraints until after the solution has been selected.

Use a heuristic because it guarantees the same result every time.

Use an algorithm because the task is well-defined and has a reliable procedure.

Use trial and error because checking possibilities is always the most efficient approach.

Use analogy because every familiar task has the same solution.

True

False

Change several factors at once and repeat the same guesses.

Keep trying actions without recording results so each attempt is independent.

Change one relevant factor at a time, record what was tried, and use the outcome to guide the next attempt.

Choose the first action that seems plausible and stop regardless of the result.

Start with the arrival time, estimate the travel time, and use that to determine when to leave.

Leave at a convenient time, then adjust the destination to match the arrival time.

Try different routes without considering the required arrival time.

List every possible destination before deciding when to depart.

Treat the entire project as one task and wait until it is finished to check progress.

Repeat the first step until the whole project is complete.

Choose a familiar method even if it does not fit the project.

Divide the project into manageable steps and track which steps are complete.

True

False
