Perhaps you should try some spelling variations:
"modified objective optimisation algorithmssssss" » "modified objective optimization algorithms", "modified objective optimization algorithmssssss", "modified multiobjective optimization algorithmssssss", "modified objective optimization algorithmsssssss", "modified objective estimation algorithmssssss", "modified objective estimation algorithmsssssss"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective optimisation algorithmssssss") OR ("defined network optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimisation algorithmssssss\") OR (\"defined network optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimisation algorithmssssss ) OR ( defined network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithmssssss") OR ("defined network optimisation algorithm"))*.
