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