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