Perhaps you should try some spelling variations:
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive 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"

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 df simulation algorithm\") OR (\"modified passive quantization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified df simulation algorithm ) OR ( modified passive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified df simulation algorithm") OR ("modified passive quantization algorithm"))*.
