Perhaps you should try some spelling variations:
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"
"modified seird estimation algorithms" » "modified seird estimation algorithm", "modified seird optimization algorithms", "modified seird optimisation algorithm", "modified sphere estimation algorithms", "modified risk estimation algorithms", "modified near estimation algorithms"

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

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