Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ estimation algorithms", "_ estimation algorithm", "_ optimized algorithms"
"qoe optimisation algorithm" » "qoe estimation algorithm", "qoe estimation algorithms", "qoe optimization algorithm", "_ optimisation algorithm", "game optimization algorithm"
"_ optimize algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm", "_ optimise 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 (\"_ optimize algorithms\"))) OR (\"qoe optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ optimization algorithms ) OR ( _ optimize algorithms ))) OR ( qoe optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimization algorithms") OR ("_ optimize algorithms"))) OR ("qoe optimisation algorithm"))*.
