2.2.2 (Computational Methods)

Question 1

What are the different computational methods used to solve computable problems?

Answer 1

-Abstraction
-Decomposition
-Enumeration
-Theoretical approach
-Simulation and automation

Question 2

How are abstraction and decomposition used to solve computable problems?

Answer 2

Simplify the complexity of a problem Break problems down

Question 3

How is enumeration used to solve computable problems?

Answer 3

Involved designing an algorithm that performs an exhaustive search and attempts all possible solutions until the correct one is found

Question 4

How is theoretical approach used to solve computable problems?

Answer 4

Certain problems can be represented using mathematical equations

Question 5

How are simulation and automation used to solve computable problems?

Answer 5

• Simulation is the process of designing a model of a real system in an attempt to understand its behaviour.
• Automation is about building problem-solving models and putting them into action.
• Both simulation and automation tend to make heavy use of abstraction and are ways of turning complex problems into ones that can be more easily solved by algorithms.
