Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
cover estimations » pose estimation
qoe optimization » game optimization, _ optimization, stage optimization
jose estimation » pose estimation, risk estimation, pulses estimation

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: "\"((\\"qoe optimization algorithms\\") or (\\"((jose estimation) OR (cover estimations)) algorithm\\"))\"".
• Removing quotes may allow a broader search: (( qoe optimization algorithms ) or ( ((jose estimation) OR (cover estimations)) algorithm )).
