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