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

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

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