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

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

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