Perhaps you should try some spelling variations:
"modified a convolution algorithms" » "modified a evolution algorithm", "modified a solution algorithm", "modified d convolutional algorithms", "modified _ convolution algorithms", "modified df convolution algorithms", "modified adam convolution algorithms"
"modified adamdaptive estimation algorithm" » "modified adaptive estimation algorithm", "modified _damdaptive estimation algorithm", "modified dfdamdaptive estimation algorithm", "modified adamdamdaptive estimation 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 adamdaptive estimation algorithm") or ("modified a convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adamdaptive estimation algorithm") OR ("modified a convolution algorithms")).
• Removing quotes may allow a broader search: (( modified adamdaptive estimation algorithm ) or ( modified a convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adamdaptive estimation algorithm") or ("modified a convolution algorithms"))*.
