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