Perhaps you should try some spelling variations:
"modified network approximation algorithm" » "modified network approximation algorithms", "certified network approximation algorithm", "defined network approximation algorithm", "modified near approximation algorithm"
"modified deep convolution algorithms" » "modified deep evolution algorithm", "modified deep solution algorithm", "modified deep convolutional algorithms", "modified delphi convolution algorithms", "modified df convolution algorithms", "modified near convolution 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 deep convolution algorithms") or ("modified network approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified deep convolution algorithms") OR ("modified network approximation algorithm")).
• Removing quotes may allow a broader search: (( modified deep convolution algorithms ) or ( modified network approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified deep convolution algorithms") or ("modified network approximation algorithm"))*.
