Perhaps you should try some spelling variations:
"modified _ optimization algorithmss" » "modified _ optimisation algorithm", "modified _ estimation algorithms", "modified _ estimation algorithm", "modified _ optimisation algorithms", "modified _ estimation algorithmss"
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"

You may be able to get more results by adjusting your search query.

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