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