Perhaps you should try some spelling variations:
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation algorithm"
"modified passive solution algorithm" » "modified passive evolution algorithm", "modified passive convolution algorithms", "modified passive evolutionary algorithm", "modified adaptive solution algorithm", "modified positive solutions algorithm", "modified saline solution 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 passive solution algorithm") OR ("modified objective predation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive solution algorithm\") OR (\"modified objective predation algorithm\"))".
• Removing quotes may allow a broader search: (( modified passive solution algorithm ) OR ( modified objective predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive solution algorithm") OR ("modified objective predation algorithm"))*.
