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