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

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: "((((\"_ optimization algorithms\") OR (\"_ optimized algorithm\"))) OR (\"qoe optimization algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ optimization algorithms ) OR ( _ optimized algorithm ))) OR ( qoe optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimization algorithms") OR ("_ optimized algorithm"))) OR ("qoe optimization algorithm"))*.
