Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ optimization algorithms", "_ optimisation algorithm", "_ approximation algorithms"
"qoe optimized algorithm" » "qoe optimized algorithms", "qoe optimizer algorithms", "_ optimized algorithm"
"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.

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