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"
"modified passive optimisation algorithm" » "modified passive optimization algorithms", "modified passive estimation algorithm", "modified passive estimation algorithms", "modified adaptive optimisation 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 algorithmss") OR ("modified passive optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimisation algorithmss\") OR (\"modified passive optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimisation algorithmss ) OR ( modified passive optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithmss") OR ("modified passive optimisation algorithm"))*.
