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 invasive optimisation algorithm" » "modified invasive optimization algorithms", "modified invasive estimation algorithm", "modified invasive 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 algorithm\") OR (\"modified invasive optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified graph convolutional algorithm ) OR ( modified invasive optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified graph convolutional algorithm") OR ("modified invasive optimisation algorithm"))*.
