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

Try widening your search to All Fields.

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 algorithmssss") or ("defined network optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimisation algorithmssss") OR ("defined network optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified objective optimisation algorithmssss ) or ( defined network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithmssss") or ("defined network optimisation algorithm"))*.
