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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( _ ((optimisation algorithm) OR (optimization algorithms)) ) OR ( qoe optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( _ ((optimisation algorithm) OR (optimization algorithms)) ) OR ( qoe optimization algorithm ))*.
