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