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