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