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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("qoe estimation algorithms") or ("qoe estimation algorithm"))) or ("_ optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("qoe estimation algorithms") OR ("qoe estimation algorithm"))) OR ("_ optimisation algorithm")).
• Removing quotes may allow a broader search: (((( qoe estimation algorithms ) or ( qoe estimation algorithm ))) or ( _ optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("qoe estimation algorithms") or ("qoe estimation algorithm"))) or ("_ optimisation algorithm"))*.
