Perhaps you should try some spelling variations:
"modified static optimisation algorithm" » "modified static optimization algorithms", "modified static estimation algorithm", "modified static estimation algorithms", "modified static optimization algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm"
"modified notion optimization algorithmsssssssss" » "modified network optimization algorithmsssssssss", "modified policy optimization algorithmsssssssss", "modified allocation optimization algorithmsssssssss"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified notion optimization algorithmsssssssss") OR ("modified static optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified notion optimization algorithmsssssssss\") OR (\"modified static optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified notion optimization algorithmsssssssss ) OR ( modified static optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithmsssssssss") OR ("modified static optimisation algorithm"))*.
