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

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

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