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