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

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