Perhaps you should try some spelling variations:
"modified notion optimization algorithmss" » "modified notion optimization algorithms", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithmss", "modified policy optimization algorithmss", "modified allocation optimization algorithmss"
"modified invasive optimisation algorithm" » "modified invasive optimization algorithms", "modified invasive estimation algorithm", "modified invasive estimation algorithms", "modified passive 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 invasive optimisation algorithm") OR ("modified notion optimization algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified invasive optimisation algorithm\") OR (\"modified notion optimization algorithmss\"))*".
• Removing quotes may allow a broader search: (( modified invasive optimisation algorithm ) OR ( modified notion optimization algorithmss ))*.
