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