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 objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation 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 objective allocation algorithm\") OR (\"modified graph convolutional algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective allocation algorithm ) OR ( modified graph convolutional algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithm") OR ("modified graph convolutional algorithm"))*.
