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

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 parameter optimizer algorithms") OR ("modified motion optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified parameter optimizer algorithms ) or ( modified motion optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimizer algorithms") or ("modified motion optimisation algorithm"))*.
