Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"mapping learning predators algorithm" » "mapping learning predation algorithm", "mapping marine predators algorithm", "machine learning predators algorithm", "enabling learning predators 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: "((\"mapping learning predators algorithm\") OR (\"modified objective convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( mapping learning predators algorithm ) OR ( modified objective convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("mapping learning predators algorithm") OR ("modified objective convolution algorithms"))*.
