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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"qoe optimizer algorithmss\") OR (\"qoe optimized algorithm\"))) OR (\"_ optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (((( qoe optimizer algorithmss ) OR ( qoe optimized algorithm ))) OR ( _ optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimizer algorithmss") OR ("qoe optimized algorithm"))) OR ("_ optimisation algorithm"))*.
