Module Description: 
This module explores techniques for the analysis and design of efficient techniques to solve reallife problems. In this module the learner will be introduced to the complexity of solving hard combinatorial problems, i.e., recognise and prove NPhard problems. Additionally, the module covers effective and efficient metaheuristic techniques to tackle complex decision problems, especially combinatorial optimisation problems. 
Learning Outcomes 
On successful completion of this module the learner will be able to: 
LO1 
Categorise a reallife problem with respect to its computational complexity. 
LO2 
Assess the benefits and limitations of metaheuristics to solve NPhard problems. 
LO3 
Solve an NPhard problem with metaheuristics to find a satisfactory lowerbound solution. 
LO4 
Analyse the average performance of a randomised algorithm to solve an NPhard problem 
LO5 
Apply natureinspired and local search metaheuristics to solve reallife problems.

Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s). 
No recommendations listed 
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
