Perhaps you should try some spelling variations:
"modified time approximation algorithm" » "modified time approximation algorithms", "modified one approximation algorithm", "modified _ approximation algorithm", "modified bi1 approximation algorithm", "modified male approximation algorithm"
"modified trained convolutional algorithm" » "modified trained convolution algorithms", "modified trained evolution algorithm", "modified trained evolutionary algorithm", "modified graph convolutional algorithm", "modified traces convolutional 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 trained convolutional algorithm") or ("modified time approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified trained convolutional algorithm") OR ("modified time approximation algorithm")).
• Removing quotes may allow a broader search: (( modified trained convolutional algorithm ) or ( modified time approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified trained convolutional algorithm") or ("modified time approximation algorithm"))*.
