Perhaps you should try some spelling variations:
"modified adamdamdamdaptive quantization algorithm" » "modified adamdamdamdaptive estimation algorithm"
"modified _ simulation algorithms" » "modified _ estimation algorithms", "modified _ optimization algorithms", "modified _ estimation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified _ simulation algorithms") OR ("modified adamdamdamdaptive quantization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified _ simulation algorithms\") OR (\"modified adamdamdamdaptive quantization algorithm\"))".
• Removing quotes may allow a broader search: (( modified _ simulation algorithms ) OR ( modified adamdamdamdaptive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified _ simulation algorithms") OR ("modified adamdamdamdaptive quantization algorithm"))*.
