Perhaps you should try some spelling variations:
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive quantization algorithm"
"modified changing solution algorithm" » "modified changing evolution algorithm", "modified changing convolution algorithms", "modified changing evolutionary algorithm", "modified caging solution algorithm", "modified charging station 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 changing solution algorithm") OR ("modified passive quantization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified changing solution algorithm\") OR (\"modified passive quantization algorithm\"))".
• Removing quotes may allow a broader search: (( modified changing solution algorithm ) OR ( modified passive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified changing solution algorithm") OR ("modified passive quantization algorithm"))*.
