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