Perhaps you should try some spelling variations:
"modified trained convolutional algorithms" » "modified trained convolution algorithms", "modified trained evolution algorithm", "modified trained evolutionary algorithm", "modified graph convolutional algorithms", "modified traces convolutional algorithms"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"

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 trained convolutional algorithms") OR ("modified objective estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified trained convolutional algorithms ) or ( modified objective estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified trained convolutional algorithms") or ("modified objective estimation algorithm"))*.
