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