Perhaps you should try some spelling variations:
"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"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective solution algorithm") OR ("mapping learning predation algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective solution algorithm ) or ( mapping learning predation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithm") or ("mapping learning predation algorithm"))*.
