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 learning evolution algorithm" » "modified learning solution algorithm", "modified learning evolutionary algorithm", "modified learning convolution algorithms", "modified learning convolution algorithm", "modified learning emotion algorithm", "mobile learning evolution algorithm", "modified caging evolution algorithm"

Try widening your search to All Fields.

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

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