Perhaps you should try some spelling variations:
"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"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimisation algorithm", "modified objective estimation algorithm", "modified objective estimation algorithms"

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