Perhaps you should try some spelling variations:
"modified objective optimizer algorithms" » "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimization algorithms", "modified objective optimal algorithms"
"modified optimal solution algorithms" » "modified optimal solution algorithm", "modified optimal evolution algorithm", "modified optimal convolution algorithms", "modified thermal solution algorithms"

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