Perhaps you should try some spelling variations:
"defined network optimization algorithmsss" » "defined network optimization algorithms", "defined network optimisation algorithm", "defined network estimation algorithms", "defined network optimization algorithmssss", "defined network optimisation algorithmsss", "defined network estimation algorithmsss", "designed network optimization algorithmsss"
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters 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 algorithmsss") or ("modified parameter optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("defined network optimization algorithmsss") OR ("modified parameter optimization algorithm")).
• Removing quotes may allow a broader search: (( defined network optimization algorithmsss ) or ( modified parameter optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("defined network optimization algorithmsss") or ("modified parameter optimization algorithm"))*.
