Perhaps you should try some spelling variations:
"_ optimizer algorithms" » "_ optimized algorithms", "_ optimization algorithms", "_ optimize algorithms", "_ optimise algorithms"
"qoe optimized algorithm" » "qoe optimized algorithms", "_ optimized algorithm"
"qoe estimation algorithm" » "pose estimation algorithm", "_ estimation algorithm", "cover estimations 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 ("_ optimizer algorithms"))) or ("qoe estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("qoe optimized algorithm") OR ("_ optimizer algorithms"))) OR ("qoe estimation algorithm"))*.
• Removing quotes may allow a broader search: (((( qoe optimized algorithm ) or ( _ optimizer algorithms ))) or ( qoe estimation algorithm ))*.
