Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified motion optimization algorithms" » "modified motion optimisation algorithm", "modified motion estimation algorithms", "modified motion estimation algorithm", "modified motion optimisation algorithms", "modified motion estimation algorithmss", "modified policy optimization algorithms", "modified allocation 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 parameters optimization algorithm") OR ("modified motion optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) or ( modified motion optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithm") or ("modified motion optimization algorithms"))*.
