Perhaps you should try some spelling variations:
"qoe optimisation algorithm" » "qoe optimization algorithms", "qoe estimation algorithms", "qoe optimization algorithm", "_ optimisation algorithm", "game optimization algorithm"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ optimization 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.

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