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 adaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive quantization 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 adaptive estimation algorithm") OR ("modified graph convolutional algorithms"))~.
• Removing quotes may allow a broader search: (( modified adaptive estimation algorithm ) or ( modified graph convolutional algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive estimation algorithm") or ("modified graph convolutional algorithms"))*.
