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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified graph convolutional algorithm") OR ("modified network optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified graph convolutional algorithm\") OR (\"modified network optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified graph convolutional algorithm ) OR ( modified network optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified graph convolutional algorithm") OR ("modified network optimization algorithms"))*.
