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

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

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