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"

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 algorithmssss") OR ("modified objective optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified network optimization algorithmssss\") OR (\"modified objective optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified network optimization algorithmssss ) OR ( modified objective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimization algorithmssss") OR ("modified objective optimization algorithms"))*.
