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