Perhaps you should try some spelling variations:
"modified near estimation algorithms" » "modified near estimation algorithm", "modified near optimization algorithms", "modified near optimisation algorithm", "modified seird estimation algorithms", "modified adam estimation 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified passive solution algorithm") OR ("modified near estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive solution algorithm\") OR (\"modified near estimation algorithms\"))*".
• Removing quotes may allow a broader search: (( modified passive solution algorithm ) OR ( modified near estimation algorithms ))*.
