Perhaps you should try some spelling variations:
"modified objective optimisation algorithmss" » "modified objective optimization algorithms", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified objective optimization algorithmss", "modified multiobjective optimization algorithmss", "modified objective optimization algorithmsss", "modified objective estimation algorithmss", "modified objective estimation algorithmsss"
"defined network optimisation algorithm" » "defined network optimization algorithms", "defined network estimation algorithm", "defined network estimation algorithms", "defined network optimization 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 optimisation algorithmss\") OR (\"defined network optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimisation algorithmss ) OR ( defined network optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithmss") OR ("defined network optimisation algorithm"))*.
