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