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

Try widening your search to All Fields.

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 algorithm") or ("modified parameter optimization algorithmsssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("defined network optimization algorithm") OR ("modified parameter optimization algorithmsssss")).
• Removing quotes may allow a broader search: (( defined network optimization algorithm ) or ( modified parameter optimization algorithmsssss )).
• Adding a wildcard symbol may retrieve word variants: (("defined network optimization algorithm") or ("modified parameter optimization algorithmsssss"))*.
