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 solution algorithm" » "modified model evolution algorithm", "modified model convolution algorithms", "modified model evolutionary algorithm", "modified male solution algorithm", "modified model solutions algorithm", "modified nodal solution algorithm", "modified model 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 solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective optimized algorithms ) or ( modified model solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithms") or ("modified model solution algorithm"))*.
