Perhaps you should try some spelling variations:
"modified parameters optimized algorithms" » "modified parameters optimized algorithm", "modified parameters optimizer algorithms", "modified parameters optimization algorithms"
"modified passive solution algorithm" » "modified passive evolution algorithm", "modified passive convolution algorithms", "modified passive evolutionary algorithm", "modified adaptive solution algorithm", "modified positive solutions algorithm", "modified saline 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 passive solution algorithm\") OR (\"modified parameters optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( modified passive solution algorithm ) OR ( modified parameters optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive solution algorithm") OR ("modified parameters optimized algorithms"))*.
