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

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