Perhaps you should try some spelling variations:
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near optimization algorithm"
"modified parameters optimized algorithm" » "modified parameters optimized algorithms", "modified parameters optimizer algorithms"

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

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