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