Perhaps you should try some spelling variations:
"modified early solution algorithm" » "modified early evolution algorithm", "modified early convolution algorithms", "modified early evolutionary algorithm", "modified male solution algorithm", "modified near solution algorithm", "modified nacl solution algorithm"
"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 early solution algorithm\") OR (\"modified parameter approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified early solution algorithm ) OR ( modified parameter approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified early solution algorithm") OR ("modified parameter approximation algorithms"))*.
