Perhaps you should try some spelling variations:
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective solution algorithm"
"modified based predation algorithm" » "modified based predators algorithm", "modified based estimation algorithm", "modified based prediction algorithm", "modified based gradation algorithm", "modified male predation 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 based predation algorithm") OR ("modified objective allocation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified based predation algorithm\") OR (\"modified objective allocation algorithm\"))*".
• Removing quotes may allow a broader search: (( modified based predation algorithm ) OR ( modified objective allocation algorithm ))*.
