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

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

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