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