Perhaps you should try some spelling variations:
"modified objective solution algorithms" » "modified objective evolution algorithm", "modified objective convolution algorithms", "modified objective estimation algorithms", "modified objective evolutionary algorithms", "modified objective allocation algorithms", "modified objective evolution algorithms", "modified objective convolution algorithmss"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms"

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