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

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 ("_ estimation algorithms"))) or ("_ optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("qoe estimation algorithms") OR ("_ estimation algorithms"))) OR ("_ optimisation algorithm"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"qoe estimation algorithms\") OR (\"_ estimation algorithms\"))) or (\"_ optimisation algorithm\"))*".
• Removing quotes may allow a broader search: (((( qoe estimation algorithms ) OR ( _ estimation algorithms ))) or ( _ optimisation algorithm ))*.
