Perhaps you should try some spelling variations:
"modified _daptive quantization algorithm" » "modified _daptive estimation algorithm", "modified adaptive quantization algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified df simulation algorithm" » "modified df estimation algorithm", "modified df solution algorithm", "modified df optimisation algorithm", "modified _ simulation algorithm", "modified a simulation algorithm", "modified 3d simulation algorithm", "modified adam simulation algorithm", "modified bi1 simulation 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 df simulation algorithm") or ("modified _daptive quantization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df simulation algorithm") OR ("modified _daptive quantization algorithm")).
• Removing quotes may allow a broader search: (( modified df simulation algorithm ) or ( modified _daptive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified df simulation algorithm") or ("modified _daptive quantization algorithm"))*.
