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