Perhaps you should try some spelling variations:
"modified passive optimisation algorithmss" » "modified passive optimization algorithms", "modified passive estimation algorithms", "modified passive estimation algorithm", "modified passive optimization algorithmsss", "modified passive estimation algorithmss", "modified passive estimation algorithmsss", "modified adaptive optimisation algorithmss"
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"

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