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

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 algorithmss\") OR (\"modified multiobjective estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( designed network estimation algorithmss ) OR ( modified multiobjective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network estimation algorithmss") OR ("modified multiobjective estimation algorithms"))*.
