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