Perhaps you should try some spelling variations:
"modified objective evolutionary algorithm" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective evolutionary algorithm") OR ("modified objective predation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective evolutionary algorithm\") OR (\"modified objective predation algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective evolutionary algorithm ) OR ( modified objective predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective evolutionary algorithm") OR ("modified objective predation algorithm"))*.
