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