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", "designed network optimization algorithmssss"
"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: (("defined network optimization algorithmssss") OR ("modified parameters optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"defined network optimization algorithmssss\") OR (\"modified parameters optimization algorithms\"))".
• Removing quotes may allow a broader search: (( defined network optimization algorithmssss ) OR ( modified parameters optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("defined network optimization algorithmssss") OR ("modified parameters optimization algorithms"))*.
