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 parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified trained convolutional algorithm") or ("modified parameter optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified trained convolutional algorithm") OR ("modified parameter optimization algorithm")).
• Removing quotes may allow a broader search: (( modified trained convolutional algorithm ) or ( modified parameter optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified trained convolutional algorithm") or ("modified parameter optimization algorithm"))*.
