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