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