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