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

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 parameter approximation algorithms\") OR (\"modified seird optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified parameter approximation algorithms ) OR ( modified seird optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter approximation algorithms") OR ("modified seird optimization algorithms"))*.
