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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("qoe optimized algorithm") OR ("qoe optimizer algorithms"))) OR ("_ optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"qoe optimized algorithm\") OR (\"qoe optimizer algorithms\"))) or (\"_ optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (((( qoe optimized algorithm ) OR ( qoe optimizer algorithms ))) or ( _ optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimized algorithm") OR ("qoe optimizer algorithms"))) or ("_ optimisation algorithm"))*.
