Perhaps you should try some spelling variations:
"modified objective evolution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective convolution algorithms", "modified objective estimation algorithm"
"mapping learning solution algorithm" » "mapping learning convolution algorithms", "mapping learning evolutionary algorithm", "mapping learning estimation algorithm", "mapping learning convolution algorithm", "mapping learning emotion algorithm", "machine learning solution algorithm", "enabling learning solution algorithm"

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 evolution algorithm") OR ("mapping learning solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective evolution algorithm ) or ( mapping learning solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective evolution algorithm") or ("mapping learning solution algorithm"))*.
