Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
qoe optimisation » qoe optimization, _ optimisation, game optimization
cover estimation » cover estimations, pose estimation, sphere estimation

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( qoe optimisation algorithm ) or ( cover estimation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe optimisation algorithm ) OR ( cover estimation algorithms ))*.
