Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"qoe optimizer algorithms" » "qoe optimized algorithm", "qoe optimization algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimization 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 optimizer algorithms") or ("_ optimized algorithms"))) or ("_ optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("qoe optimizer algorithms") OR ("_ optimized algorithms"))) OR ("_ optimisation algorithm")).
• Removing quotes may allow a broader search: (((( qoe optimizer algorithms ) or ( _ optimized algorithms ))) or ( _ optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimizer algorithms") or ("_ optimized algorithms"))) or ("_ optimisation algorithm"))*.
