Perhaps you should try some spelling variations:
"_ optimizer algorithms" » "_ optimized algorithm", "_ optimization algorithms", "_ optimized algorithms", "_ optimize algorithms", "_ optimise algorithms"
"qoe optimized algorithms" » "qoe optimized algorithm", "qoe optimization algorithms", "_ optimized algorithms"
"jose estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "cover estimations algorithm"

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