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

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

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