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

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

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