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"
"designed network estimation algorithms" » "designed network estimation algorithm", "designed network optimization algorithms", "designed network optimisation algorithm", "defined network estimation algorithms"

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

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