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

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: "((\"_ optimized algorithms\") OR (((\"qoe estimation algorithms\") OR (\"_ optimization algorithms\"))))~".
• Removing quotes may allow a broader search: (( _ optimized algorithms ) OR ((( qoe estimation algorithms ) OR ( _ optimization algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("_ optimized algorithms") OR ((("qoe estimation algorithms") OR ("_ optimization algorithms"))))*.
