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