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 make solution algorithm" » "modified make evolution algorithm", "modified make convolution algorithms", "modified make evolutionary algorithm", "modified male solution algorithm", "modified water solution algorithm", "modified nacl solution algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimized algorithms\") OR (\"modified make solution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimized algorithms ) OR ( modified make solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithms") OR ("modified make solution algorithm"))*.
