Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified graph evolution algorithm" » "modified graph solution algorithm", "modified graph evolutionary algorithm", "modified graph convolution 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 optimized algorithm") OR ("modified graph evolution algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( modified graph evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") or ("modified graph evolution algorithm"))*.
