Perhaps you should try some spelling variations:
"modified notion optimisation algorithm" » "modified notion optimization algorithms", "modified notion estimation algorithm", "modified notion estimation algorithms", "modified network optimization algorithm"
"modified risk optimized algorithms" » "modified risk optimized algorithm", "modified risk optimizer algorithms", "modified risk optimization algorithms", "modified write optimized algorithms", "modified bi1 optimized 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 risk optimized algorithms") OR ("modified notion optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified risk optimized algorithms\") OR (\"modified notion optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified risk optimized algorithms ) OR ( modified notion optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified risk optimized algorithms") OR ("modified notion optimisation algorithm"))*.
