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

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("robust optimisation algorithm") or ((("qoe optimized algorithm") OR ("_ optimized algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("robust optimisation algorithm") OR ((("qoe optimized algorithm") OR ("_ optimized algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"robust optimisation algorithm\") or (((\"qoe optimized algorithm\") OR (\"_ optimized algorithm\"))))".
• Removing quotes may allow a broader search: (( robust optimisation algorithm ) or ((( qoe optimized algorithm ) OR ( _ optimized algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("robust optimisation algorithm") or ((("qoe optimized algorithm") OR ("_ optimized algorithm"))))*.
