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 caging evolution algorithm" » "modified caging solution algorithm", "modified caging evolutionary algorithm", "modified caging convolution algorithms", "modified aging evolution algorithm", "modified changing evolution algorithm", "modified charging evolution 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 algorithm\") OR (\"modified caging evolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimized algorithm ) OR ( modified caging evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithm") OR ("modified caging evolution algorithm"))*.
