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 parameter optimized algorithms" » "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimization 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 trained convolutional algorithms") OR ("modified parameter optimized algorithms"))~.
• Removing quotes may allow a broader search: (( modified trained convolutional algorithms ) or ( modified parameter optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified trained convolutional algorithms") or ("modified parameter optimized algorithms"))*.
