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