Perhaps you should try some spelling variations:
"_ estimation algorithmss" » "_ estimation algorithms", "_ optimization algorithms"
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithms", "_ optimization algorithm"
"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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("qoe estimation algorithm") OR ((("_ estimation algorithmss") OR ("_ optimisation algorithm"))))~.
• Removing quotes may allow a broader search: (( qoe estimation algorithm ) or ((( _ estimation algorithmss ) or ( _ optimisation algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("qoe estimation algorithm") or ((("_ estimation algorithmss") or ("_ optimisation algorithm"))))*.
