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 multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified graph convolutional algorithms\") OR (\"modified multiobjective optimizer algorithms\"))~".
• Removing quotes may allow a broader search: (( modified graph convolutional algorithms ) OR ( modified multiobjective optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified graph convolutional algorithms") OR ("modified multiobjective optimizer algorithms"))*.
