Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithms » optimization algorithms, estimation algorithms, estimation algorithm
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
qoe optimisation » qoe optimization, _ optimisation, game optimization

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( qoe optimisation algorithm ) or ( parameters optimisation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe optimisation algorithm ) OR ( parameters optimisation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( qoe optimisation algorithm ) or ( parameters optimisation algorithms ))*.
