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