Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ optimization algorithm"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ approximation algorithms"
"qoe optimized algorithms" » "qoe optimized algorithm", "qoe optimizer algorithms", "qoe optimization algorithms", "_ optimized 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: (("qoe optimized algorithms") or ((("_ optimisation algorithm") OR ("_ estimation algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("qoe optimized algorithms") OR ((("_ optimisation algorithm") OR ("_ estimation algorithms")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"qoe optimized algorithms\") or (((\"_ optimisation algorithm\") OR (\"_ estimation algorithms\"))))".
• Removing quotes may allow a broader search: (( qoe optimized algorithms ) or ((( _ optimisation algorithm ) OR ( _ estimation algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("qoe optimized algorithms") or ((("_ optimisation algorithm") OR ("_ estimation algorithms"))))*.
