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