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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("mapping learning evolution algorithm") OR ("modified objective optimal algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping learning evolution algorithm\") OR (\"modified objective optimal algorithm\"))".
• Removing quotes may allow a broader search: (( mapping learning evolution algorithm ) OR ( modified objective optimal algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mapping learning evolution algorithm") OR ("modified objective optimal algorithm"))*.
