Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ estimation algorithms", "_ estimation algorithm", "_ optimizer algorithms"
"qoe optimisation algorithm" » "qoe estimation algorithm", "qoe estimation algorithms", "qoe optimization algorithm", "_ optimisation algorithm", "game optimization algorithm"
"_ optimized algorithms" » "_ optimized algorithm", "_ 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: (("qoe optimisation algorithm") or ((("_ optimization algorithms") or ("_ optimized algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("qoe optimisation algorithm") OR ((("_ optimization algorithms") OR ("_ optimized algorithms")))).
• Removing quotes may allow a broader search: (( qoe optimisation algorithm ) or ((( _ optimization algorithms ) or ( _ optimized algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("qoe optimisation algorithm") or ((("_ optimization algorithms") or ("_ optimized algorithms"))))*.
