Perhaps you should try some spelling variations:
"modified rough approximations algorithms" » "modified rough approximation algorithms", "modified rough approximation algorithm", "modified one approximation algorithms"
"modified learning convolution algorithm" » "modified learning convolution algorithms", "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithm", "modified caging 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 rough approximations algorithms") OR ("modified learning convolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified rough approximations algorithms\") OR (\"modified learning convolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified rough approximations algorithms ) OR ( modified learning convolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified rough approximations algorithms") OR ("modified learning convolution algorithm"))*.
