Perhaps you should try some spelling variations:
"_ optimized algorithmss" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithmsss", "_ optimizer algorithmsss"
"qoe optimized algorithm" » "qoe optimized algorithms", "qoe optimizer algorithms"
"sphere estimation algorithm" » "pose estimation algorithm"

You may be able to get more results by adjusting your search query.

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