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