Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithm » optimisation algorithm, estimation algorithm, estimation algorithms
optimized algorithm » optimized algorithms, optimizer algorithms
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: "(( cover ((optimization algorithms) OR (optimized algorithm)) ) OR ( qoe optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( cover ((optimization algorithms) OR (optimized algorithm)) ) OR ( qoe optimization algorithm ))*.
