Perhaps you should try some spelling variations:
"modified motion optimisation algorithm" » "modified motion optimization algorithms", "modified motion estimation algorithm", "modified motion estimation algorithms"
"modified changing optimized algorithm" » "modified changing optimized algorithms", "modified changing optimizer algorithms", "modified choosing optimizer algorithm", "modified caging optimized algorithm"

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

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