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 notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"

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 notion estimation algorithms") or ("modified trained convolutional algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion estimation algorithms") OR ("modified trained convolutional algorithms")).
• Removing quotes may allow a broader search: (( modified notion estimation algorithms ) or ( modified trained convolutional algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithms") or ("modified trained convolutional algorithms"))*.
