Perhaps you should try some spelling variations:
"modified adam optimisation algorithm" » "modified adam optimization algorithms", "modified adam estimation algorithm", "modified adam estimation algorithms", "modified _ optimisation algorithm", "modified game optimization algorithm", "modified df optimisation algorithm", "modified near optimisation algorithm"
"modified graph convolution algorithms" » "modified graph evolution algorithm", "modified graph solution algorithm", "modified graph convolutional algorithms"

Try widening your search to All Fields.

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

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