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 network estimation algorithms" » "modified network estimation algorithm", "modified network optimization algorithms", "modified network optimisation algorithm", "certified network estimation algorithms", "defined network estimation algorithms", "modified near 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: (("modified network estimation algorithms") OR ("modified learning convolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified network estimation algorithms\") OR (\"modified learning convolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified network estimation algorithms ) OR ( modified learning convolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified network estimation algorithms") OR ("modified learning convolution algorithm"))*.
