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