Perhaps you should try some spelling variations:
"modified objective convolution algorithmss" » "modified objective convolution algorithms", "modified objective evolution 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 predation algorithm") OR ("modified objective convolution algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective predation algorithm\") OR (\"modified objective convolution algorithmss\"))*".
• Removing quotes may allow a broader search: (( modified objective predation algorithm ) OR ( modified objective convolution algorithmss ))*.
