Perhaps you should try some spelling variations:
"modified parameters optimization algorithmssss" » "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified parameter optimization algorithmssss", "modified parameter estimation algorithmssss"
"modified network estimation algorithm" » "modified network optimization algorithm", "certified network estimation algorithm", "defined network estimation algorithm", "modified near estimation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified network estimation algorithm\") OR (\"modified parameters optimization algorithmssss\"))~".
• Removing quotes may allow a broader search: (( modified network estimation algorithm ) OR ( modified parameters optimization algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network estimation algorithm") OR ("modified parameters optimization algorithmssss"))*.
