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