Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified passive quantization algorithmsss" » "modified adaptive quantization algorithmsss", "modified passive quantization algorithm", "modified passive quantization algorithmic"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective convolution algorithms") OR ("modified passive quantization algorithmsss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective convolution algorithms\") OR (\"modified passive quantization algorithmsss\"))".
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) OR ( modified passive quantization algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective convolution algorithms") OR ("modified passive quantization algorithmsss"))*.
