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 simulation algorithms" » "modified df estimation algorithms", "modified df optimization algorithms", "modified df estimation algorithm", "modified _ simulation algorithms", "modified a simulation algorithms", "modified 3d simulation algorithms", "modified adam simulation algorithms", "modified bi1 simulation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified df simulation algorithms") or ("modified dfdamdaptive quantization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df simulation algorithms") OR ("modified dfdamdaptive quantization algorithm")).
• Removing quotes may allow a broader search: (( modified df simulation algorithms ) or ( modified dfdamdaptive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified df simulation algorithms") or ("modified dfdamdaptive quantization algorithm"))*.
