Perhaps you should try some spelling variations:
"modified motion optimization algorithms" » "modified motion optimisation algorithm", "modified motion estimation algorithms", "modified motion estimation algorithm", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified allocation estimation algorithmss" » "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimization algorithmss", "modified motion estimation algorithmss"

Try widening your search to All Fields.

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

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