Perhaps you should try some spelling variations:
"modified df convolutional algorithm" » "modified df evolution algorithm", "modified df evolutionary algorithm", "modified d convolutional algorithm", "modified deep convolutional algorithm", "modified _ convolutional algorithm", "modified adam convolutional algorithm", "modified bi1 convolutional algorithm"
"modified passive convolution algorithms" » "modified passive evolution algorithm", "modified passive solution algorithm", "modified adaptive convolution 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 df convolutional algorithm") or ("modified passive convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df convolutional algorithm") OR ("modified passive convolution algorithms")).
• Removing quotes may allow a broader search: (( modified df convolutional algorithm ) or ( modified passive convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified df convolutional algorithm") or ("modified passive convolution algorithms"))*.
