Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified time estimation algorithm" » "modified pose estimation algorithm", "modified risk estimation algorithm", "modified motion estimation algorithm", "modified bi1 estimation algorithm", "modified male estimation 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 time estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) or ( modified time estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective convolution algorithms") or ("modified time estimation algorithm"))*.
