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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified graph convolutional algorithms\") OR (\"modified adaptive optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified graph convolutional algorithms ) OR ( modified adaptive optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified graph convolutional algorithms") OR ("modified adaptive optimisation algorithm"))*.
