Perhaps you should try some spelling variations:
"qoe optimisation algorithm" » "qoe optimization algorithms", "qoe optimization algorithm", "_ optimisation algorithm", "game optimization algorithm"
"_ estimation algorithms" » "_ optimization algorithms", "_ approximation algorithms"
"qoe estimation algorithm" » "pose estimation algorithm", "cover estimations algorithm", "qoe optimization 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 optimisation algorithm") or ("_ estimation algorithms"))) or ("qoe estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("qoe optimisation algorithm") OR ("_ estimation algorithms"))) OR ("qoe estimation algorithm")).
• Removing quotes may allow a broader search: (((( qoe optimisation algorithm ) or ( _ estimation algorithms ))) or ( qoe estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimisation algorithm") or ("_ estimation algorithms"))) or ("qoe estimation algorithm"))*.
