Perhaps you should try some spelling variations:
"mapping learning convolution algorithm" » "mapping learning convolution algorithms", "mapping learning solution algorithm", "machine learning convolution algorithm", "enabling learning convolution algorithm"
"modified objective evolution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective solution algorithm", "modified objective convolution 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 convolution algorithm") or ("modified objective evolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("mapping learning convolution algorithm") OR ("modified objective evolution algorithm"))*.
• Removing quotes may allow a broader search: (( mapping learning convolution algorithm ) or ( modified objective evolution algorithm ))*.
