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