Perhaps you should try some spelling variations:
"modified static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static estimation algorithm", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing optimization algorithms"
"modified graph convolutional algorithm" » "modified graph convolution algorithms", "modified graph evolution algorithm", "modified graph evolutionary algorithm", "modified deep convolutional algorithm", "modified trained convolutional algorithm"

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

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