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