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