Perhaps you should try some spelling variations:
"modified objective convolution algorithmss" » "modified objective evolution algorithm", "modified objective evolution algorithms", "modified objective solution algorithms"
"mobile learning convolution algorithms" » "mobile learning evolution algorithm", "mobile learning solution algorithm", "machine learning convolution algorithms"

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: "((\"mobile learning convolution algorithms\") OR (\"modified objective convolution algorithmss\"))~".
• Removing quotes may allow a broader search: (( mobile learning convolution algorithms ) OR ( modified objective convolution algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("mobile learning convolution algorithms") OR ("modified objective convolution algorithmss"))*.
