2.2.2 Computational methods - Filip

Question 1

define decomposition

Answer 1

breaking down a large problem into lots of small problem which re more manageable

Question 2

define abstraction

Answer 2

ignoring insignificant/ unnecessary details

Question 3

define back tracking

Answer 3

methodically going down every possible path then going back on yourself once you find an error

Question 4

define data mining

Answer 4

a technique used to find anomalies/ patterns in large sets of data

Question 5

define hueristics

Answer 5

rules of thumb which are a non exact result

Question 6

define pipelining

Answer 6

different tasks being undertaken at the same time to improve efficiency

Question 7

define performance modelling

Answer 7

Performance modelling eliminates the need for true performance testing by providing
mathematical methods to test a variety of loads on different operating systems.

Question 8

what’s divide and conquer

Answer 8

in this context divide and conquer refers to a way of decomposition involving divining then solving then merging parts of a larger problem back together
