Perhaps you should try some spelling variations:
"modified static estimation algorithmssss" » "modified static estimation algorithms", "modified static estimation algorithm", "modified static optimization algorithmssss"
"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 algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithm") OR ("modified static estimation algorithmssss")).
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) or ( modified static estimation algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithm") or ("modified static estimation algorithmssss"))*.
