Perhaps you should try some spelling variations:
"modified motion estimation algorithmssss" » "modified motion estimation algorithms", "modified motion estimation algorithm", "modified notion estimation algorithmssss"
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"

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 objective convolution algorithms") OR ("modified motion estimation algorithmssss"))~.
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) or ( modified motion estimation algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective convolution algorithms") or ("modified motion estimation algorithmssss"))*.
