Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"modified graph convolutional algorithms" » "modified graph convolution algorithms", "modified graph evolution algorithm", "modified graph evolutionary algorithm", "modified deep convolutional algorithms", "modified trained convolutional algorithms"

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 multiobjective optimizer algorithms") OR ("modified graph convolutional algorithms"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimizer algorithms ) or ( modified graph convolutional algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimizer algorithms") or ("modified graph convolutional algorithms"))*.
