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

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