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 adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive optimization algorithms") or ("modified graph convolutional algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive optimization algorithms") OR ("modified graph convolutional algorithm")).
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithms ) or ( modified graph convolutional algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimization algorithms") or ("modified graph convolutional algorithm"))*.
