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

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

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