Perhaps you should try some spelling variations:
"modified df convolutional algorithms" » "modified df convolution algorithms", "modified df evolution algorithm", "modified df evolutionary algorithm", "modified d convolutional algorithms", "modified deep convolutional algorithms", "modified _ convolutional algorithms", "modified adam convolutional algorithms", "modified bi1 convolutional algorithms"
"modified parameter estimation algorithm" » "modified parameter estimates algorithm", "modified parameter optimization algorithm"

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

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