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

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