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