Perhaps you should try some spelling variations:
"modified objective optimized algorithms" » "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimization algorithms", "modified objective optimal algorithms"
"modified model selection algorithm" » "modified model solution algorithm", "modified model estimation algorithm", "modified model reduction algorithm", "modified market selection algorithm", "modified male selection 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 algorithms") OR ("modified model selection algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective optimized algorithms ) or ( modified model selection algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithms") or ("modified model selection algorithm"))*.
