Perhaps you should try some spelling variations:
"modified _fdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified _fdaptive estimation algorithm"
"modified adam solution algorithm" » "modified adam evolution algorithm", "modified adam convolution algorithms", "modified adam evolutionary algorithm", "modified df solution algorithm", "modified near solution algorithm", "modified nodal solution 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 _fdaptive quantization algorithm\") OR (\"modified adam solution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified _fdaptive quantization algorithm ) OR ( modified adam solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified _fdaptive quantization algorithm") OR ("modified adam solution algorithm"))*.
