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