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