Perhaps you should try some spelling variations:
"modified dfdamdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dfdamdaptive estimation algorithm", "modified _damdaptive quantization algorithm", "modified adamdamdaptive quantization algorithm", "modified bi1damdaptive quantization algorithm"
"modified df evolution algorithm" » "modified df solution algorithm", "modified df evolutionary algorithm", "modified df convolution algorithms", "modified _ evolution algorithm", "modified co evolution algorithm", "modified adam evolution algorithm", "modified bi1 evolution 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 dfdamdaptive quantization algorithm") or ("modified df evolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified dfdamdaptive quantization algorithm") OR ("modified df evolution algorithm")).
• Removing quotes may allow a broader search: (( modified dfdamdaptive quantization algorithm ) or ( modified df evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified dfdamdaptive quantization algorithm") or ("modified df evolution algorithm"))*.
