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