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 algorithm" » "_ optimized algorithms", "_ optimizer algorithms"
"risk estimation algorithm" » "pose estimation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"qoe optimisation algorithm\") OR (\"_ optimized algorithm\"))) OR (\"risk estimation algorithm\"))~".
• Removing quotes may allow a broader search: (((( qoe optimisation algorithm ) OR ( _ optimized algorithm ))) OR ( risk estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimisation algorithm") OR ("_ optimized algorithm"))) OR ("risk estimation algorithm"))*.
