Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithm", "_ optimized algorithms"
"qoe estimation algorithms" » "qoe estimation algorithm", "qoe optimisation algorithm", "qoe approximation algorithms", "pose estimation algorithms", "_ estimation algorithms", "cover estimations algorithms"
"_ optimize algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm", "_ optimise 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: "((((\"qoe estimation algorithms\") OR (\"_ optimization algorithms\"))) OR (\"_ optimize algorithms\"))~".
• Removing quotes may allow a broader search: (((( qoe estimation algorithms ) OR ( _ optimization algorithms ))) OR ( _ optimize algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("qoe estimation algorithms") OR ("_ optimization algorithms"))) OR ("_ optimize algorithms"))*.
