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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe optimisation algorithm ) OR ( smooth ((optimized algorithms) OR (optimized algorithm)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( qoe optimisation algorithm ) or ( smooth ((optimized algorithms) OR (optimized algorithm)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( qoe optimisation algorithm ) or ( smooth ((optimized algorithms) OR (optimized algorithm)) ))*.
