Perhaps you should try some spelling variations:
"modified notion optimisation algorithmss" » "modified notion optimization algorithms", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified notion optimization algorithmsss", "modified notion estimation algorithmss", "modified notion estimation algorithmsss", "modified network optimization algorithmss"
"modified _ optimisation algorithm" » "modified _ optimization algorithms", "modified _ estimation algorithm", "modified _ 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 _ optimisation algorithm") OR ("modified notion optimisation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified _ optimisation algorithm\") OR (\"modified notion optimisation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified _ optimisation algorithm ) OR ( modified notion optimisation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified _ optimisation algorithm") OR ("modified notion optimisation algorithmss"))*.
