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