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