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