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 estimation algorithm" » "modified invasive ventilation algorithm", "modified passive estimation algorithm"

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

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