Computational methods

Question 1

Backtracking

Answer 1

Trying out a sequences of actions and determining how far they succeed until it becomes apparent that it can go no further. Backtracking is essentially trial and error

Question 2

Data mining

Answer 2

The process of examining large data sets looking for patterns and relationships.

Question 3

Performance modelling

Answer 3

consists of predicting the way software behaves when in use by analysing program functions and using Big O notation to show how algorithms behave with bigger sizes of input.

Question 4

Pipelining

Answer 4

is a common technique where the output of one process can be fed into another. Complex jobs can be divided up into separate pipelines so that parallel processing can occur.

Question 5

Visualisation

Answer 5

problems and data can often be better understood when translated into a visual model, which can show unexpected and interesting trends that could not be produced by traditional manual methods
