computational methods

Question 1

problem decomposition

Answer 1

decompose problem into smaller subproblems so it is easier to solve,test,debug and maintain

Question 2

divide and conquer

Answer 2

uses recursion to split the problem into seaprate task, each task is then sorted and combined to make a solution

Question 3

use of abstraction

Answer 3

removing unnecessary pieces of data and keeping relevant pieces of data
saves memory,solve problem faster,reduce complexity

Question 4

backtracking

Answer 4

uses recursion to move from one part of the problem to another
only used for sequential problems

Question 5

Data mining

Answer 5

searching through unconnected data searching for correlations between components
the analysis of large data to provide new information

Question 6

heuristics

Answer 6

guessing the best approach to solve a problem by reducing computation time

Question 6

performance modelling

Answer 6

simulating or modelling the performance of a system before it is used

Question 7

Identify ways performance modelling could be used to test the new system

Answer 7

Testing it with a large number of simultaneous orders (stress testing)
Testing it with a large number of customers/items/orders

Question 8

use of computational methods

Answer 8

costs effective
time saving
but requires accurate data
