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