Computational Methods

Question 1

Problem definition

Answer 1

Process of taking a big problem and breaking it down into smaller problems

Question 2

Performance modelling

Answer 2

Process of carrying out mathematical approximations of how well models perform.

Based around the use of simulations- using mathematical approximations within them without having to perform complex and expensive for testing which otherwise might be prohibitive.

Question 3

Heuristics

Answer 3

Making use of experience to find a solution which is good enough

With heuristics a compromise between the speed of the solution and the quality itself is made. A good enough solution is sought

Question 4

Pipelining

Answer 4

Process of taking a task and splitting it up into smaller steps and then overlapping the process of each sub task to speed up the overall process.

Question 5

Visualisation

Answer 5

Ability to picture a problem and it’s solution in a visual way

We work well with visual representations of complex situations

Question 6

Backtracking

Answer 6

Process of incrementally building upwards to a solution abandoning partial successes

When the solution cant be completed, go back to a previously successful match.

Question 7

Data mining

Answer 7

Searching through big data to spot hidden trends or patterns

Big data- Large piece of data on a particular data.
