Perhaps you should try some spelling variations:
"motion optimisation algorithm" » "motion optimization algorithms", "motion estimation algorithm", "motion estimation algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"
"_ optimise algorithm" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimize algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("motion optimisation algorithm") or ((("_ optimise algorithm") or ("_ optimized algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("motion optimisation algorithm") OR ((("_ optimise algorithm") OR ("_ optimized algorithm")))).
• Removing quotes may allow a broader search: (( motion optimisation algorithm ) or ((( _ optimise algorithm ) or ( _ optimized algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("motion optimisation algorithm") or ((("_ optimise algorithm") or ("_ optimized algorithm"))))*.
