Perhaps you should try some spelling variations:
"modified adamdamdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified adamdamdaptive estimation algorithm"
"modified exact convolution algorithms" » "modified exact evolution algorithm", "modified exact solution algorithm", "modified exact solution algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adamdamdaptive quantization algorithm\") OR (\"modified exact convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified adamdamdaptive quantization algorithm ) OR ( modified exact convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adamdamdaptive quantization algorithm") OR ("modified exact convolution algorithms"))*.
