Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
pulses estimation » pose estimation
poses estimation » pose estimation, cover estimations, risk estimation
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: "\"((\\"((poses estimation) OR (pulses estimation)) algorithm\\") or (\\"qoe optimization algorithm\\"))\"".
• Removing quotes may allow a broader search: (( ((poses estimation) OR (pulses estimation)) algorithm ) or ( qoe optimization algorithm )).
