Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified graph convolutional algorithm" » "modified graph convolution algorithms", "modified graph evolution algorithm", "modified graph evolutionary algorithm", "modified deep convolutional algorithm", "modified trained convolutional algorithm"

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