Perhaps you should try some spelling variations:
"modified caging optimization algorithms" » "modified caging optimisation algorithm", "modified caging estimation algorithms", "modified caging estimation algorithm", "modified staffing optimization algorithms"
"modified graph convolution algorithms" » "modified graph evolution algorithm", "modified graph solution algorithm", "modified graph convolutional algorithms"

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 caging optimization algorithms") OR ("modified graph convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified caging optimization algorithms ) or ( modified graph convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified caging optimization algorithms") or ("modified graph convolution algorithms"))*.
