Perhaps you should try some spelling variations:
"modified charging convolution algorithms" » "modified charging evolution algorithm", "modified charging solution algorithm", "modified learning convolution algorithms", "modified caging convolution algorithms", "modified carbon convolution algorithms"
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"

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