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