Perhaps you should try some spelling variations:
"defined network optimization algorithmss" » "defined network optimisation algorithm", "defined network estimation algorithms", "defined network estimation algorithm", "defined network optimisation algorithms", "defined network estimation algorithmss"
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation 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 parameters optimization algorithms") OR ("defined network optimization algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameters optimization algorithms\") OR (\"defined network optimization algorithmss\"))".
• Removing quotes may allow a broader search: (( modified parameters optimization algorithms ) OR ( defined network optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithms") OR ("defined network optimization algorithmss"))*.
