Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
optimization algorithm » optimization algorithms, estimation algorithm, optimized algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
qoe optimization » game optimization, _ optimization, stage 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 optimization algorithm ) OR ( pose ((estimation algorithms) OR (optimisation algorithm)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( qoe optimization algorithm ) or ( pose ((estimation algorithms) OR (optimisation algorithm)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( qoe optimization algorithm ) or ( pose ((estimation algorithms) OR (optimisation algorithm)) ))*.
