Perhaps you should try some spelling variations:
"modified network optimization algorithmsss" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithms", "modified network optimization algorithmssss", "modified network optimisation algorithmsss", "modified network estimation algorithmsss", "certified network optimization algorithmsss", "defined network optimization algorithmsss", "modified near optimization algorithmsss"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified network optimization algorithmsss") or ("modified objective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimization algorithmsss") OR ("modified objective optimization algorithm")).
• Removing quotes may allow a broader search: (( modified network optimization algorithmsss ) or ( modified objective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimization algorithmsss") or ("modified objective optimization algorithm"))*.
