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

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: "((\"modified objective optimization algorithmss\") OR (\"defined network optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimization algorithmss ) OR ( defined network optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithmss") OR ("defined network optimization algorithm"))*.
