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 solution algorithm" » "modified deep evolution algorithm", "modified deep convolution algorithms", "modified deep evolutionary algorithm", "modified delphi solution algorithm", "modified df solution algorithm", "modified near solution algorithm", "modified drug solution algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified deep solution algorithm") OR ("modified network approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified deep solution algorithm ) or ( modified network approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified deep solution algorithm") or ("modified network approximation algorithm"))*.
